Comprehensive Regionalization of Torreya grandis ‘Merrillii' Cultivation Based on Climate, Terrain and Soil Factors by GIS Technology in Zhejiang Province
摘要
Abstract
Torreya grandis ' Merrillii' is an indigenous economic tree species in Zhejiang Province, but its potential economic value is not fully obtained because of the irrational regional distribution. The evaluation system of comprehensive regionalization was constructed according to its biological characteristics and the requirement to environmental factors which mainly included three climate factors, two topography factors and two soil factors. These regionalization indices were gridded by the mixed interpolation method. An evaluation model of comprehensive regionalization was established by using the index accumulation method (IAM ). Taking account of the land use condition and eliminating the unsuitable planting regions, the results mainly included three grades of the suitable region, sub-suitable region and unsuitable region. The refined regionalization map was drew by using CIS technology, and the regionalization indices were calculated according to the grids of 100 m x 100 m. The results of this study would provide a scientific basis for the production of Torreya grandis ' Merrillii' in Zhejiang Province.关键词
