Aim of the study: To show that the Oasis in Xinjiang of China is facing serious sustainable development challenges due to the climate change and human activities, especially for the drought stress. Material and methods: Linear trend method, also known as linear trend forecasting method and linear fitting, is the most studied and popular quantitative forecasting method so far. Based on the time series data during the observation period, it is assumed that the predicted variables have a linear function relationship with time, and is fitted into a straight line, so that the straight line can reflect the changing trend of the variables themselves, namely, a linear regression model. Results and conclusions: From 1961 to 2016, Aksu Oasis climate in general showed a "warm and wet" trend. From 1991 to 2016, the oasis area continued to expand, and the desert area showed a decreasing trend, and land use changed significantly. The regional water resources have obviously changed, and the average groundwater depth in the oasis area was between 3.55 and 4.35 meters, showing an increasing trend, while the groundwater level was decreasing. Water resources shortage is the most fundamental reason to restrict the expansion of oasis scale. The suitable oasis scale of Aksu Oasis in 1991, 2001 and 2016 is 12611.30, 15949.95 and 16631.59 km2, respectively, but the actual area of the oasis in the three periods is larger.
研究目的:研究新疆绿洲在气候变化和人类活动的双重影响下,特别是干旱胁迫下,面临着严峻的可持续发展挑战。材料与方法:线性趋势法又称线性趋势预测法、线性拟合法,是目前研究最多、应用最广泛的定量预测方法。根据观测期间的时间序列数据,假设预测变量与时间呈线性函数关系,并拟合成一条直线,使直线能够反映变量本身的变化趋势,即线性回归模型。结果与结论:1961—2016年阿克苏绿洲气候总体上呈现“暖湿化”趋势。1991 - 2016年绿洲面积持续扩大,荒漠面积呈减少趋势,土地利用变化明显。区域水资源变化明显,绿洲区地下水平均深度在3.55 ~ 4.35 m之间,呈增加趋势,而地下水位呈下降趋势。水资源短缺是制约绿洲规模扩大的最根本原因。1991年、2001年和2016年阿克苏绿洲适宜绿洲规模分别为12611.30 km2、15949.95 km2和16631.59 km2,但3个时期绿洲实际面积较大。

Aim of the study: In the present study, the spatial – temporal variations of water quality in Boyalı Pond were analyzed. Water Quality Index (WQI) based on the World Health Organization's standards specified for drinking water, and Water Quality Control Regulations in Turkey (WQCR), as well as certain multi-statistical methods, were used in analyzing the water quality. Material and methods: Water samples were collected from 5 stations selected in the lake on monthly basis in 2019 and 30 water quality parameters were measured in total. Water Quality Index (WQI), Factor Analysis (FA), and Cluster Analysis (CA) were used in order to determine the differences between the spatial and temporal quality levels and to classify the investigated locations. Results and conclusions: According to data observed, Boyalı Dam Lake was found to have Class I and Class II water quality in general the WQI results obtained suggested that, although the water quality was found to significantly decrease in summer months, the reservoir was found to have an "A Grade – Excellent" water quality (<50) in all the months and stations analyzed here. WQI values recorded in the dam lake ranged between 16.4 and 27.8 and the detected limnologic parameters did not exceed the standards specified for drinking water in any of the investigated months and stations (<50 for WQI). As a result of FA, 3 factors explained 88.9% of total variances and as a result of CA, 2 statistical clusters were formed.
研究目的:分析了博雅尔比池塘水质的时空变化特征。水质分析采用了以世界卫生组织规定的饮用水标准为基础的水质指数(WQI)和土耳其水质控制条例(WQCR)以及若干多重统计方法。材料与方法:2019年逐月在该湖泊选取5个站点采集水样,共测量30个水质参数。采用水质指数(WQI)、因子分析(FA)和聚类分析(CA)等方法确定了水质时空差异,并对调查地点进行了分类。结果与结论:根据观测数据,博雅尔尔湖总体水质为一类和二类,WQI结果表明,虽然夏季月份水质明显下降,但在分析的月份和站点中,水库水质均为“A级-优”(<50)。坝湖WQI值在16.4 ~ 27.8之间,各调查月份和站点的湖泊参数均未超过饮用水标准(WQI <50)。由于FA, 3个因素解释了总方差的88.9%,由于CA,形成了2个统计聚类。

Aim of the study. Indication of changes in maize yield for grain and silage in connection with the observed climate changes. Material and methods.Data from field experiments of the experimental station of the University of Warmia and Mazury since 1972 as well as meteorological data (air temperatures and precipitation). Calculations using the trend analysis of original variables and determined indexes (GDD, SPI, Sielianinov index), weather-yield linear models and elements of spectral analysis. Results and conclusions. Changes in thermal conditions were demonstrated based on average air temperatures and the GDD index. There were no significant changes in atmospheric precipitation, showing a small periodicity of ten years, and no changes in monthly frequency with a deficit of precipitation (SPI analysis). It was demonstrated that changes in thermal conditions as well as the introduction of new maize varieties over fifty years significantly improved plant maturation, which resulted in a significant increase in grain weight. However, this did not affect the yield of maize for silage, neither in crop rotation nor in the monoculture system.
研究的目的。指示与观测到的气候变化有关的谷物和青贮玉米产量变化。材料和方法。瓦姆尼亚和马祖里大学实验站1972年以来的野外试验资料以及气象资料(气温和降水)。利用原始变量和确定指标(GDD、SPI、Sielianinov指数)的趋势分析、天气-产量线性模型和光谱分析要素进行计算。结果和结论。根据平均气温和gdp指数,论证了热条件的变化。大气降水变化不显著,表现为10年的小周期,月频次无变化,存在降水亏缺(SPI分析)。结果表明,50多年来,热条件的变化和玉米新品种的引进显著促进了植株的成熟,从而导致籽粒重的显著增加。然而,这并不影响青贮玉米的产量,无论是在轮作还是在单一栽培系统中。

Aim of the study: In this research, spatial – temporal variations of water quality in Yassıalan Dam Lake were investigated by determining a total of 28 limnologic parameters and by using Water Quality Index (WQI) and Principle Component (PCA). Material and methods: Water samples were collected from seven stations selected on the reservoir monthly in 2018 – 2019 and total of 28 water quality parameters were measured in water samples. WQI was used for evaluating the water quality by using the parameters of pH, EC, Cl, NO2, NO3, SO4, Na, Pb, Cu, Cd, Hg, Ni, Zn and PCA was used for evaluating the water quality by using the variables of pH, BOD, EC, salinity, dissolved oxygen, total hardness, temperature, total alkalinity, Hg, Ca, NO3, NO2, NH4, SO4, Mg, Ca, Fe, Ni, Cl, Zn, Cd, S, Na, K, Pb, Cu. Results and conclusions: According to data observed, water of the Yassıalan Dam Lake has 1st – 2nd Class water quality in general and according to the results of WQI, although it was determined that the water quality decreased significantly in summer period, the reservoir was found as "A Grade – Excellent" water quality (<50) in all the investigated months and at all the investigated stations. WQI values recorded in the dam lake were found as 15.3 – 26.1 and the detected limnologic parameters did not exceed the specified drinking water standards in all the investigated months and at all the investigated stations. According to the results of PCA, 3 factors explained 84.2% of total variances.
