资源与环境综合承载力分析——以银川滨河新区总体规划为例

从自然、经济、社会环境承载力3个方面构建资源与环境承载力评价指标体系,利用层次分析法和相对比较法,确定指标体系的权重;利用模糊综合评价法和关联分析法,计算评价体系中各指标的承载力指数,最后,得出环境承载力指数,此外,对自然、经济和社会环境承载力之间的协调度进行分析。结果表明:伴随着区域发展模式的优化调整,银川滨河新区资源与环境承载力指数呈上升趋势,区域环境承载能力逐步增强,各承载力系统之间属于良好协调状态,自然、经济、社会环境系统呈良性循环的可持续发展态势。

Comprehensive Bearing Capacity of Resource and Environment in Riverfront District of Yinchuan

In this paper,an evaluation index system of comprehensive bearing capacity of resource and environment was established from the aspects of natural,economic and social environmental bearing capacities.Weight of the index system was determined by use of AHP and relative comparison method.Bearing capacity index of each indicator in the evaluation system was calculated by application of fuzzy comprehensive evaluation and association analysis.Then,environmental bearing capacity index was obtained.In addition,the coordination degree between natural,economic and social environmental bearing capacities was analyzed.The results showed that with optimization and adjustment of the regional development pattern,the bearing capacity index of resource and environment in Riverfront District of Yinchuan appeared with a rising trend.The regional environmental bearing capacities were enhanced gradually with the bearing capacity systems in good coordination conditions.Natural,economic and social environment systems showed a sustainability tendency in a virtuous cycle.
