四川省汶川地震重灾区人居环境适宜性评价
|
摘要
"5.12"汶川地震对区域生态环境和人文景观造成明显损害,区域生态脆弱性增大,山地灾害风险升级,影响人居环境的安全和灾后重建的布局。选取地震灾害危险性、次生山地灾害危险性、可利用土地资源、可利用水资源、环境容量承载力、生态系统脆弱性、生态重要性、经济发展水平、人口聚集度、交通优势度等10大评价因子,应用G IS技术,采用关键因子与权重分析相结合的评价方法,建立评价模型,A=n∑i=1Ai×Wi对"5.12"地震重灾区人居环境适宜性进行综合评价。结果表明:重灾区人居适宜区和较适宜区位于东部平原、丘陵区;中等适宜区主要位于丘陵、低山、西北部高原及龙门山前过渡区;适宜性较差区和差区基本位于龙门山高山峡谷区。根据人居适宜性分区结果,讨论了各适宜区灾后重建的产业、城镇布局及人口规模。
"5·12" Wenchuan Earthquake obviously damaged the ecological environment and human landscape.Consequently,the ecological environment became more fragile and the mountain hazards became more dangerous.The earthquake had influenced the safety of human settlements and the reconstructed layout of disaster area.This article evaluated comprehensively the suitability of human settlements in the heavy disaster of Wenchuan earthquake that selected main factors(disasters danger of earthquake,secondary mountain hazards,using land resources,available water resources,environmental capacity,ecosystem fragility,ecological significance,economic development level,population density,traffic dominance),applied the technology of geographic information system and adopted the evaluation method of key factors combined with weight factors,and established the model of evaluation(A=∑ni=1Ai×Wi).The results showed that: The suitable regions and more suitable regions allocated in the eastern plain and hilly areas.The moderate suitable regions located in low mountain,hilly areas,western plateau and the transition region of Longmenshan piedmont.The regions which are not suitable and worse suitable located in the alpine-gorge area.According to the results of human settlements,the industrial layout,urban spatial distribution and population scale are discussed in the article.
