土地环境质量综合评价模型的建立--以山东半岛蓝色经济区为例
摘要
Abstract
Based on multi purpose regional geochemical survey data,comprehensive evaluation method of land environment quality has been studied,and comprehensive evaluation model has been established.A new idea were first proposed that land environment quality comprehensive evaluation is soil internal classi-fication,external indicators grading and integrating all the evaluation factors.By using correlation coeffi-cient,semivariance function index selection,analytic hierarchy process (ahp)to determine the contestant indexes weights,the membership function model is set up to different content units indicators into the same evaluation system,overlaying regional groundwater and crop quality of external factors,land quality evaluation model is established.According to the established model to comprehensive evaluating the Jia-odong peninsula land environment quality,the results show that the Jiaodong peninsula land can be divided into high quality,excellent,good,intermediate ,poor ,5 ,etc.,which can be made the green level (1 1 1 and 121)and free (211 and 221)food production base of land accounted for 62.60%;needing agricultural planting structure adjustment of 512 and 522 level land area is 267.54 km2,which are more than around all kinds of mining area (gold,graphite ore,copper ore)or adjacent to the villages and towns.Land environ-ment quality comprehensive evaluation method and model has certain reference significance to Shandong other parts of basic farmland protection and land quality hierarchy.关键词
