Suitability Evaluation of Tuber Mustard Cultivation in Fuling Based on Grey Relation and Principal Component Analysis
摘要
Abstract
To study the suitable planting zones of Fulingtuber mustard,its suitable climate was discussed in this study.Based on the grey relational analysis and principal component analysis,combining with 19 bioclimatic indices,suitable planting zones and suitable climate of tuber mustard in Fulingwere evaluated comprehensively.It indicated that the climatic suitability of 421 village communities of Fuling should bedivided into three categories by the equal-weight correlation degree and comprehensive evaluation model.Category Ⅰ(high suitable zone,λ≥0.913)included Zengfu,west of Shituo,Yihe,south of Maan,Longqiao,Chongyi,Jiangbei,northwest of Nantuo,southeast of Baisheng,southest of Zhenxi,part of Baitao,part of Lizhi,part of Jiangdong;category Ⅱ(moderate suitable zone,0.764≤λ<0.913)included Zengfu,northwest of Shituo,north of Yihe,Lidu,north of Maan,north of Linshi,most of Lizhi,south of Jiangdong,northeast of Baitao,southwest of Jiaoshi;category Ⅲ(low suitable zone,λ<0.764)included Longtan,Tongle,Qingyang,Mawu,Wulingshan,Damu,Luoyun,Jiaoshi,northwest of Baisheng,Northwest of Zhenxi.The northwest and northeast of Fuling are the better zones for the tuber mustard planting.The results can provide a reference for the reasonable layout of the tuber mustardproduction in Fuling,and promote the healthy and sustainable development of the industry.关键词
