基于GIS的祁门县茶叶种植适宜性评价

摘要

On the basis of data from Soil Test and Formula Fertilization project in Qimen county, we employed Geographic Information System　Software ArcGIS 9.2 and CLRMIS (Cultivated Land Resource Management Information System at County Scale) to establish region-specific estimation index system for tea cultivation in Qimen County by determining the estimation units, and carried out quantitative estimation analysis on　tea cultivation there via comprehensive evaluation indices for natural elements of cultivated land. The results showed that the highly suitable, suitable, reluctantly suitable and unsuitable acreages are 5 665.8, 8 327.1,8 415.9 and 11 979.9 hm2 respectively, accounting for 24.0％, 35.3％, 35.7％ and 5.1％ of the total acreage of cultivated land. These results would facilitate the production of high yield and quality tea in Qimen County.%运用ArcGIS地理信息系统软件以及"县域耕地资源管理信息系统",利用祁门县"测土配方施肥"项目的采样调查分析结果,该研究通过确定评价单元,建立了具有区域特色的评价指标体系,并采用耕地自然要素评价综合指数法,对祁门县茶叶种植进行定量评价分析.结果表明:高度适宜、适宜、勉强适宜和不适宜的面积分别为5 665.8、8 327.1、8 415.9和1 197.9 hm2,分别占耕地总面积的24%、35.3%、35.7%和5.1%.该研究结果将有助于祁门县高产优质茶叶的生产.
