摘要
人为干预对农业系统的影响表现为粮食不安全,由于研究区域城市化的扩大,当地市场的作物生产成本增加,对居住用地的需求在9年内达到2.66%。此外,除了这个模拟结果之外,森林砍伐对城市农业和生计的影响并没有在埃塞俄比亚南部高地及其周围的大部分地区进行科学研究,特别是在Wolayta地区,sodo zuria worda显示,每年0.295%的林地减少了0.09%,用于住宅用地,并在选定的研究期间用于公共服务。本文研究了埃塞俄比亚农业转型(ATP)可持续发展目标背景下城市化率和土地利用、土地覆被变化对地理空间环境的负面影响,利用灵长类和次级数据源,结合GIS地理信息系统和遥感方法进行了检测分析。而图像分类精度的评价可以定义为将分类图像与通常认为准确且具有参考价值的地理数据进行比较的过程,将分类图像的数据与基于监督分类的地真值进行比较,其像元(CR)一致性比为0.016%,对30m Land Sat 7卫星图像进行精度评价。通常,一组参考shapefile被叠加为7个主要的土地利用类,这些土地利用类是通过计算特征向量矩阵的AHP方法在分类图像上生成的,这是成对比较矩阵的输出,根据列出的土地利用面积的像素值产生最佳拟合集
Impacts of Urbanization Rate and Land Cover Change on Urban Farm Land: A Case of Wolayta Zone Sodo Zuria Woreda
The effect of human intervention on the agricultural system has shown food insecurity with an increase in the cost of crop production in the local market due to the expansion of urbanization in the study area with 2.66% in 9 years for the demand of residential land. and also beyond this simulation result, the impact of deforestation on urban Agricultural and livelihoods was not scientifically studied in most of the southern Ethiopia high lands and their surrounding in particularly for Wolayta zone sodo zuria woreda has shown 0.295 % per year of forestland declined by 0.09 % for residential land and it has used for public service during the selected study period. This study has focused on the impact of urbanization rate and land use land cover change detection analysis using Primate and secondary data source with integration (GIS) Geographic Information System and Remote sensing Method for managing the negative impact on the geospatial environment in the context of Ethiopian Agricultural Transformation (ATP) goal of sustainable development. And evaluation of image classification accuracy can be defined as the process of comparing the classified image with geographic data considered to be accurate and referential typically, the data which is classified image is compared to are ground-truth based on supervised classification with (CR) Consistency Ratio 0.016 % of the pixel has resulted for accuracy assessment of 30m Land Sat 7 satellite image. In general, a set of reference shapefile has been overlaid as 7 major landuse class which are generated over the classified image by the AHP method of Computing Eigenvector Matrixes, which is an output of the pairwise comparison matrix to produce the best fit set based on the pixel value landuse area listed
