GIS-Based Suitability Evaluation of Tea Garden in Changting County
摘要
Abstract
An integrated evaluation of the orchard,woodland and grassland was performed for suitability of tea garden.Choosing 11 evaluation indexes from 5 respects of landform,climate,soil and location and ecology, the suitability evaluation index system of tea garden in Changting county was establish.With the aid of GIS,an suitability evaluation model for tea garden was developed by using the principal of hierarchy analysis,fuzzy mathematics and methods of the exponential weighted algorithm.Dynamic cluster analysis was used to classify the evaluation units.The results showed that the total area of land suitable for tea production reached 167 288.21 hm2,accounting for 61.64% of the total area of the orchard,woodland and grassland in Changting,and about 33 674.52 hm2 or 20.13% was high in suitability,and 87 721.95 hm2or 52.44%,moderate in suitability.The land in "High suitability" category was mainly distributed in the regions,of Zhuotian,Nanshan,Yicheng and Tufang,totaling up to 23 535.89 hm2,or 69.89% of the category.The results can provide scientific guidance for the rational construction of tea garden and the increase of the production of tea in Changting County.关键词
