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。
