Abstract: This paper discusses Japanese CCRC, one of regional vitalizing measure in Japan. Sustainable regional managements are diffi cult in rural areas of Japan where the population is declining. In such a situation, Japanese CCRC are being worked on by local governments nationwide to enhance medical welfare and promote migration. Therefore, it is essential for Japanese CCRC to use vitalities of private sectors to create new regional attractions. Based on the above, this study clarifi es managements form through public-private partnerships according to regional characteristics of Japanese CCRC. Nationwide trends of the Japanese version of CCRC are not limited to the depopulated areas facing population decline, but it has also been implemented in areas where the population is concentrated. And, project scopes of Japanese CCRC are mostly town type, but there are few area types. Local governments that maintain populations are not only increasing number of migrants, but also trying to settle the elderly and create youth jobs. On the other hand, local governments with a declining population are trying to maintain and improve their local vitality by acquiring migrants. Town-type Japanese CCRC are working on spread of accumulated regional resources in cooperation with local companies and university institutions that can share purpose of projects. Area-type Japanese CCRC are making efforts to enhance regional services by utilizing vitality of private sectors to establish small bases and consolidate local resources.
摘要:本文探讨了日本区域振兴措施之一的日本CCRC。在人口不断减少的日本农村地区,可持续的区域管理是困难的。在这种情况下,日本各地的地方政府正在研究日本的CCRC,以提高医疗福利和促进移民。因此,日本CCRC必须利用私营部门的活力来创造新的区域吸引力。在此基础上,本研究根据日本CCRC的地域特点,明确了公私合作的管理形式。日本版的CCRC在全国范围内的趋势不仅局限于人口减少的地区,而且在人口集中的地区也得到了实施。日本CCRC的项目范围多为城镇类型,而区域类型较少。维持人口的地方政府不仅在增加外来人口,还在努力安置老年人,创造年轻人的就业机会。另一方面,人口减少的地方政府正试图通过吸引外来人口来维持和提高当地的活力。乡镇型日本CCRC正在与当地公司和大学机构合作,利用积累的区域资源,分享项目的目的。地区型日本CCRC正在努力加强区域服务,利用私营部门的活力,建立小型基地和整合地方资源。

As the Co-Creation perspective is introduced into place branding theory, researches that focus on the relationship between people and places has come to be seen. Place attachment is drawing attention as a concept to grasp the psychological connection between people and places. A previous study, the " Place brand equities and values evaluation model " has been examining the value of people to the region. However, there is not enough discussion on the relationship between this model and place attachments. This study measured place brand equities and valuation in a mountainous area, and verifi ed the relationship with place attachment. As a result, it revealed that the place brand equities factor and the value factor were interrelated, and all factors were related to the place attachment. Also, unlike the previous research, which involved place brand equities to place brand value, they were involved in each other. This suggests that local resident's assessment of place brand equities and values may interact in a two-way manner with respect to place attachments. And then the effect of personal attributes on the evaluation of place equities was suggested. On the other hand, the impact of place attachments from natural equities is low in this survey, and verifi cation in similar regions will be necessary to clarify the reason.
随着共同创造的视角被引入到场所品牌理论中,关注人与场所关系的研究开始出现。地点依恋是一种为了把握人与地点之间的心理联系而引起人们注意的概念。之前的一项研究“地方品牌资产和价值评估模型”一直在研究该地区的人的价值。然而,对该模型与地点依恋之间的关系的讨论还不够。本研究测量了一个山区的地方品牌资产和价值,并验证了与地方依恋的关系。结果表明,地方品牌权益因素与价值因素存在显著的相关性,且所有因素都与地方依恋相关。此外,与之前的研究不同的是,它们涉及到品牌资产来放置品牌价值,它们相互关联。这表明当地居民对地方品牌资产和价值的评估可能与地方依恋以双向方式相互作用。在此基础上提出了个人属性对地方公平评价的影响。另一方面,本调查中自然权益的地方依恋的影响较低,需要在类似地区进行验证以澄清原因。

An Issue of Post Classification Comparison for Land Cover Land Use Change Detection 土地覆被、土地利用变化检测的分类后比较研究

地域・農村計画策定に向けた環境把握,環境アセスメ ント実施のための環境評価,さらには近年注目されてい る生態系サービス評価 や生物多様性評価 のため, 土地被覆・土地利用(Land Cover Land Use, LCLU) 分類図の作成と土地被覆・土地利用変化(Land Cover Land Use Change. LCLUC)抽出のための方法論の確立 が求められている。LCLU分類図,LCLUC は様々な応 用研究や環境政策に活用されており,基盤となる空間情 報として極めて高精度のプロダクトが期待されている。 数多くの LCLU 分類図が公的機関,大学,研究所を通 じて公開されているが,必ずしも入手可能な LCLU 分 類図が高精度であるとは限らない。たとえば Zhao and Tsutsumidaは複数の全球 LCLU 分類図から一地域を 切り出してその利用を試みたが,その地域では LCLU が正しく分類されていなかったため,独自で LCLU 分 類図の作成が求められた。また,クラス数やクラス定義 は個々の事例に応じて対応する必要があるため,そのよ うな場合,LCLU分類図を自ら作成せざるを得ない。 LCLU分類図の作成にはリモートセンシングデータの 活用が一般的である 。衛星や航空機に備わるセンサー を用いると,一度の撮影で広域情報を入手することがで きる利点がある。光学センサーにより撮影されたデータ であれば複数の観測スペクトルの幅(観測バンド)を, 合成開口レーダーより撮影されたデータであれば地表面 からの複数の反射信号を記録している。オルソ化や大気 補正などのいくつかの処理が必要な場合があるが ,位 置情報のついた画像はピクセル単位で地表面の状況の理 解に利用することができる。空間解像度(ピクセルのサ イズ)はリモートセンシングデータの特徴の一つであ る。例えば Landsat 8 の可視域データは空間解像度がお よそ 30 m,Sentinel-2 の可視域データは約 10 mである。 すなわち,Sentinel-2 であれば約 10 × 10 m = 100 m のピクセルを単位として地表面の情報が記録されてい る。この情報から教師つき分類・教師なし分類などによ り LCLU分類図を作成する。上記のような性質により, LCLU分類図はピクセル単位で精度を評価されることが 一般的である。なお,LCLU分類はピクセルベースの分 類のほかにオブジェクトベースの分類法も存在する 。 オブジェクトベース分類は画像から均一的なエリアをセ グメントとして予め抽出し,それらに対して教師つき分 類や教師なし分類を適用するものである。以降,話を単 純化するために,ここではピクセルベース分類による LCLU分類図とその変化に着目する。 LCLUC の抽出は二時期の LCLU 分類図を比較する 分類結果比較法(Post Classifi cation Comparison, PCC) によって多く実施されてきた。PCCは,例えば時点 tの LCLU 分類図(It)と時点 t+ 1の分類図(It+1)を作成 し,この 2つの分類図をピクセルごとに比較することで LCLUが変化したか否かを分析する手法である。このよ うに PCCは非常に簡便な手法であるが,It,It+1 が正し く分類されているという前提を見過ごすことができない という課題がある 。分類器を通じて作成された LCLU 分類図は,分類誤差を免れることがほぼ不可能である し,手作業で LCLU 分類図を作成できたとしても位置 誤差やヒューマンエラーが発生する可能性を考慮すべき である。そのため,どのような LCLU 分類図において もすべてのピクセルにおいて正しく分類されているとは 想定しづらい。そこで本稿では,LCLU分類図の分類誤 差が,PCC による LCLUC の抽出にどの程度影響を及 ぼすかについて,簡単なシミュレーションを通じて示し てみたい。
为了制定地区和农村计划的环境把握,为了环境评估和实施环境评估,为了近年来备受关注的生态系统服务评估和生物多样性评估,土地覆盖和土地利用(Land Cover Land Use,LCLU)分类图的制作和土地覆盖、土地利用变化(Land Cover Land Use Change. LCLUC)提取的方法论的确立。LCLU分类图和LCLUC被广泛应用于各种应用研究和环境政策中,作为基础的空间信息,极高精度的产品备受期待。许多LCLU分类图通过公共机关、大学、研究所公开,但不一定能得到的LCLU分类图是高精度的。例如,Zhao and Tsutsumida从多个全球LCLU分类图中切出一个区域,尝试使用该区域,但由于该区域的LCLU没有被正确分类,只好独自进行LCLU分类。被要求制作类图。另外,由于类数和类定义需要根据个别事例来对应,因此在这种情况下,就不得不自己制作LCLU分类图。LCLU分类图的制作一般使用遥感数据。如果使用卫星和飞机上配备的传感器,则具有一次拍摄即可获取广域信息的优点。如果是光学传感器拍摄的数据,则记录多个观测光谱的宽度(观测带),如果是合成孔径雷达拍摄的数据,则记录来自地表的多个反射信号。虽然有时需要进行奥尔索化和大气校正等几种处理,但带有位置信息的图像可以像素为单位用于地表状况的理解。空间分辨率是遥感数据的特征之一。例如Landsat 8的可视域数据的空间分辨率为30m,Sentinel-2的可视域数据约为10m。也就是说,如果是Sentinel-2的话,是以约10 × 10m = 100m的像素为单位来记录地平面的信息。根据该信息,通过有教师分类、无教师分类等来制作LCLU分类图。根据上述性质,一般以像素为单位来评价LCLU分类图的精度。另外,LCLU分类除了基于像素的分类以外,还存在基于对象的分类法。基于对象的分类是从图像中预先提取均匀的区域作为片段,对这些区域应用有教师分类或无教师分类。以后,为了简单化,这里着眼于基于像素分类的LCLU分类图及其变化。LCLUC的提取通过比较两个时期的LCLU分类图的分类结果比较法(Post Classifi cation Comparison, PCC)被大量实施。PCC是一种制作例如时间点t的LCLU分类图(It)和时间点t+1的分类图(It+1),将这两个分类图按像素进行比较,从而分析LCLU是否发生变化的方法。PCC是一种非常简便的方法,但也存在一个问题,那就是不能忽视It、It+1被正确分类的前提。通过分类器制作的LCLU分类图几乎不可能避免分类误差,即使手工制作LCLU分类图,也应该考虑到位置误差和人为错误的可能性。就是这样。因此,无论什么样的LCLU分类图,都很难假设对所有像素进行了正确的分类。因此,本文将通过简单的模拟展示LCLU分类图的分类错误对PCC提取LCLUC有多大影响。

Characterization of the Distribution and the Habitat of Euphorbia Adenochlora as Landscape Resources in Ukiya no Sato, Kazo City, Saitama Prefecture 埼玉县和户市浮谷野佐藤景观资源大戟分布及生境特征
Pub Date : 2020-12-30 DOI: 10.2750/arp.39.320

The distribution of the wildfl ower Euphorbia adenochlora, a symbol of marshland, was investigated in the “Ukiya no Sato” rural landscape conservation area. The community scale of a total of 2,930 m was confi rmed at 8 points in the marsh with a rich spring fl ower landscape of the E. adenochlora community. The large population of E. adenochlora present was distributed over the area where the marsh has long not been reclaimed as a rice paddy; thus, it was considered that the marsh had functioned as an ecological refugium for this hydrophytic species. The tendency of high-density growth of E. adenochlora in relatively dry areas within the marsh was indicated as a result of the investigation by the grid lot in the habitat on the largest scale. Features of its location were a domination of Miscanthus saccharifl orus at the upper part, as well as high Saururus chinensis and Stachys aspera abundance. Although there was a similar external community on the site dominated by M. saccharifl orus in autumn, the fl oristic composition between abandoned paddy fi elds and habitats that continued to be marshland was different. Since Carex dispalata was dominant at lower-lying areas and the occurrence of E. adenochlora was rare in abandoned paddy fi elds, it was judged that the former was unsuitable habitat for this native wildfl ower. Conclusively, the distribution of E. adenochlora was a result of factors including a characteristic ecosystem with spring water sourced in a buried valley, the given history of rural development where non-reclaimed land has been left as refugium for a natural ecosystem to develop, as well as recent landscape conservation activities including burning by a landowner.
对“浮屋野佐藤”乡村景观保护区内湿地象征野花大戟(Euphorbia adenochlora)的分布进行了调查。在沼泽的8个点上确定了腺藻群落的群落规模,共2,930 m,具有丰富的春花景观。大量的腺藻种群分布在长期未开垦为稻田的沼泽地区;因此,沼泽被认为是这种水生植物的生态避难所。通过最大规模的生境网格样地调查,表明了沼泽内相对干燥地区腺藻高密度生长的趋势。其地理位置的特点是上部以芒草为主,中国龙和石竹的丰度较高。虽然在秋季有类似的外部群落,但荒废水田与继续为沼泽地的生境之间的群落组成不同。由于低海拔地区以苔草(Carex dispalata)为主,而废弃水田中腺藻(E. adenochlora)罕见,因此判断苔草不适合该原生野花的生境。最后,腺藻的分布是多种因素的结果,包括一个特征生态系统,泉水来源于一个埋藏的山谷,给定的农村发展历史,未开垦的土地被留下作为自然生态系统发展的避难所,以及最近的景观保护活动,包括土地所有者的焚烧。

Although there was a similar external community on the site dominated by M. saccharifl orus in autumn, the fl oristic composition between abandoned paddy fi elds and habitats that continued to be marshland was different. Since Carex dispalata was dominant at lower-lying areas and the occurrence of E. adenochlora was rare in abandoned paddy fi elds, it was judged that the former was unsuitable habitat for this native wildfl ower. Conclusively, the distribution of E. adenochlora was a result of factors including a characteristic ecosystem with spring water sourced in a buried valley, the given history of rural development where non-reclaimed land has been left as refugium for a natural ecosystem to develop, as well as recent landscape conservation activities including burning by a landowner.","PeriodicalId":272722,"journal":{"name":"JOURNAL OF RURAL PLANNING ASSOCIATION","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128497567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
