福建沿海地区农业生态环境脆弱度模糊综合评判

根据福建沿海地区农业脆弱生态环境的特点,以人均水资源、森林覆盖率、人均耕地面积、水土流失、干燥指数、农药使用量、化肥使用量、人均GDP、农民人均收入、恩格尔系数、人口密度、文盲率、高等教育率等作为评价指标,利用层次分析法分配各指标权重,通过模糊综合评判模型运算和隶属度分析,将福建沿海地区农业脆弱生态环境分为较严重脆弱、中等脆弱、一般脆弱、无脆弱4个等级.研究结果为该地区农业环境可持续发展提供科学依据.

The Fuzzy Synthetic Evaluation of Agricultural Fragile Environment in Fujian Coastal Area

According to the features of agricultural fragile environment in Fujian coastal area, makes sure the 13 evaluation indexes including per capita water resources, covered by forests, per capita cultivated areas, soil erosion, arid index, quantity of pesticide, quantity of fertilizer, per capita GDP, per capita (income) of farmer, Engel's coefficient, population density, proportion of illiteracy, proportion of high education and so on. And the weights of each index influencing agricultural fragile environment is determined with analytical hierarchy process method. Calculated by the model of the Fuzzy synthetic evaluation, the (agricultural) fragile environment in Fujian coastal area is classified into serious fragility, moderate fragility, gentle fragility and none fragility. The result will provide scientific basis for sustainable development of (agricultural) fragile environment in Fujian coastal area.
