- 摘要:
- 以典型的平原河网——温瑞塘河为例，对河道进行25 m×25 m网格化，并利用Voronoi图确定网格化河道点影响范围，从而把网格化河道点与土地利用现状、企业分布等无缝关联成一个整体。以建设用地为纽带，完成了社会经济统计数据与网格化河道点的关联和细分。以污染源普查数据为依据，实现了宏观经济与微观网格化河道点的结合。分析结果表明：温瑞塘河水环境社会压力超负载，其空间分布失衡，导致这一现象的本质是人口问题。河道网格化是城市水环境污染精细化分析、模拟与管理的有效手段。
- Abstract:
- Taking Wenruitang River as a case，the river was divided into 25 m×25 m grids.It then overlaid the grids with social and economic drivers such as current land use and industry distributions using Voronoi chart.According to the census of pollution sources，the combination of macroeconomic with micro river points was realized.The results showed that the analyzed land and industry uses had induced environmental stress on the Wenruitang River，causing it to surpass its pollution load.It was believed that the phenomenon was caused by an imbalanced spatial distribution of the population.In addition to the conclusions of this analysis，the results of this paper strongly support the usefulness of the gridding methodology as a powerful tool of analysis，able to accurately simulate and model environmental pollution associated with municipal water system management.
