中文摘要:
      为分析水资源分布空间均衡性,选取降水量指标,基于GIS空间分析和统计数据的量化分析,提出表征任意空间点或空间单元均衡程度的空间均衡系数(SSEC)和表征全区域均衡程度的总体空间均衡度(GGSED)的概念和计算方法,并以河南省为例验证了该方法的准确性。结果表明,受季风性气候、纬度和地形的影响,河南省水资源空间分布差异较大,降水量由东北部向东南部递增,东南部降水量变化较大;中部地区水资源空间分布较为均衡,空间均衡系数分别由北部、南部向中部递增。研究结果可用于指导区域水资源优化配置和经济社会空间均衡发展。
英文摘要:
      In order to analyze the equilibrium of water resources spatial distribution, precipitation was chosen as the characteristic indices. Based on GIS spatial analysis and quantitative analysis of statistic data, this article proposed the concept and computing method of spatial equilibrium coefficient (SSEC) represented the spatial equilibrium degree of arbitrary spatial point or spatial cell as well as global spatial equilibrium degree (GGSED) represented the equilibrium degree of global region. Taking Henan Province as the study area, the accuracy of this method was verified. The results show that the water resource spatial distribution in Henan Province is different because of affecting by the monsoon climate, latitude and topography. The precipitation was declined from northeast area to southeast area, and the precipitation in southeast area was changed greatly. The water resource spatial distribution in middle area was much more equalized. The spatial distribution equalization coefficient was increased from north and south area to middle area. The study can guide optimal allocation of regional water resources and spatial equilibrium development of social economy.
