基于和田地区2005年社会经济、水资源和生态环境等资料,选取21项指标构建评价指标体系,采用基于熵权的集对分析法和聚类分析法对和田地区水资源可持续利用进行评价与分析。结果表明和田地区民丰县为可持续水平,其他区域则为弱不可持续和不可持续水平。聚类分析结果显示和田地区水资源可持续利用制约类型可归为4类: 可持续型（民丰县）,受制于人口的无河型（皮山县）,受制于水资源配置型（策勒县）和受制于人口的有河型（和田河流域,于田县,和田地区）。 相似文献

新疆伊犁河流域草地类型特征及其生态服务价值研究 总被引：6，自引：0，他引：6
以新疆伊犁河流域为研究对象,采用Costanza生态系统服务价值计算公式,参照谢高地等人的中国草地生态系统服务单位面积价值,分析了伊犁河流域草地类型特征和生态系统服务价值。研究结果表明,新疆伊犁河流域草地资源丰富,草地面积占土地总面积的60.88%以上,草地产草量及载畜能力均处于全疆最好水平,其中山地草甸类草地面积最大,占草地可利用面积的27.91%。草地生态系统每年的服务价值为200.47亿元,山地草甸类草地、温性草甸草原类以及温性草原类草地生态服务价值达145.3亿元,占到全流域草地总生态服务价值的72.48%,是草地生态服务价值的主体部分,流域生态系统服务性功能远大于生产性功能。总体看来,伊犁河流域草地生态服务价值山间盆地、丘陵区较高;而平原区相对较低。草地存在退化现象,1985—2005年间草地生态服务价值有所下降。 相似文献

新疆伊犁河流域气候变化(英文) 总被引：3，自引：0，他引：3
In this paper, the monthly precipitation and temperature data collected at 7 stations in the Ili River Basin from 1961 to
2007 were analyzed by means of simple regression analysis, running mean, db6 wavelet function and Mann-Kendall test. This
study revealed the characteristics of climate change and abrupt change points of precipitation and temperature during different
time scales in the Ili River Basin within the past 50 years. The results showed that the precipitation increased from the
mid-1980s until 2000 and has continued to increase at a smaller magnitude since 2000. Over the studied period, the precipitation
increased significantly during the summer and winter months. The temperature increased greatly in the late 1980s, and has
continued to show an increasing trend from the year 2000 to present. The temperature increases were most significant during
the summer, autumn and winter months. In terms of different geographies, the temperature increase was significant during the
winter in the plains and hilly regions; the increase was also significant during autumn in the intermontane basins. The climate
change trends in the Ili River Basin were consistent with the changing trends of the North Atlantic Oscillation and the plateau
monsoon. 相似文献
