摘要/Abstract

摘要： 丝绸之路经济带横跨我国东部到西部，水土资源的空间分异特征明显，对该区域水土资源的空间分布格局和分异规律进行监测和评价，能有效地引导经济带开发的空间布局。基于GIS空间分析与统计数据定量分析，通过计算研究区各地级市的后备可利用土地资源和水资源进行分析：（1）后备可利用水土资源总量的空间分布特征及其地域分异规律；（2）人均后备可利用水土资源的空间分布格局和资源丰度分异规律；（3）人均后备可利用土地资源与水资源的分布匹配程度，以及区域人均后备可利用水土资源的空间分异规律分析。结果表明：研究区共有后备可利用土地资源309 849.6 km²，后备可利用水资源1 512.21亿m³；后备可利用水土资源人均占有量呈现由南往北、由西向东递减的趋势，水土资源空间分布不均，且土地资源与水资源的空间分布不相匹配。

Abstract: Monitoring and evaluating the spatial distribution and differentiation of the reserved land and water resources are useful for guiding the development of the Silk Road Economic Belt, because this region spans across the east to the west of our country, and the water and land resources are obviously different in space. By using the methods of spatial analysis and quantitative analysis of statistical data, and calculating the reserved land and water resources, we conducted the following analyses:(1) spatial distribution and regularity of its regional differentiation of the reserved land and water resources; (2) the spatial distribution and the resource abundance's differentiation of the reserved land and water resources per capita; (3) the matching degree of the provinces' reserved construction land and available water resource per capita, and the analyses of the reserved land and water resources' regional differentiation. The results showed that:the area of the reserved construction land was 309 849.6 km², and the available water resource was 1 512.21 billion cubic meters. The reserved land and water resources showed a trend of high value in the west while low value in the east, and high value in the south while low value in the north. The spatial distributions of the reserved construction land and available water resource were uneven, and their spatial distributions were not matched.
