| 摘 要： | 应用数学、统计学等方法建立＂比较矩阵＂分析模型,对喀斯特地区生态环境敏感性评价指标的分级方法进行研究。与此同时,以都匀市土地利用类型为例,从生物多样性、系统承载力、环境容量、气候调节、物质循环与能量流动、水土保持与流失、环境污染、土地退化等11个指标来对13种土地利用类型分别做比较分析与敏感性量化,然后进行敏感性排序和有序聚类分级,并借助GIS软件绘成都匀市土地利用类型生态敏感等级分布图。研究结果认为,级敏感的土地利用类型包括灌木林地、有林地,级敏感包括天然草地、稻田、园地、水域,级敏感包括旱地、陵墓地,级敏感包括城镇、公路、农村居民点,级敏感包括独立工矿用地、未利用地。

| Abstract: | An analyzing model of ＂contrast matrix＂ is built through mathematics and statistics method, to study grading method of the sensitivity evaluation index in karst eco-environment. Meanwhile, the land-use style in Duyun isstudied as a case. The study involves comparatively analysis and quantification of the sensi- tivity to 13 types of land-use style with the following 11 indices, biodiversity, ecosystem＇s carrying capacity, environmental capacity, climate modification, matter circulation and energy flow, soil loss, environmental pollution, land degradation and so on, and ordering the sensitivity and orderly clustering the grade, and then drawing a grading distribution map with sensitivity grade of land-use in Duyun with GIS. The result indicates that the Sensitive Grade Ⅰ includes shrub forest and forest land; the Grade Ⅱ natural grassland, paddy field, garden and water area; the Grade Ⅲ dry-land and mausoleum field; the Grade Ⅳ town, road and rural settlements; and the Grade Ⅴ mining sites and unused land. |
