摘要
为了确定茎瘤芥(榨菜)在涪陵区的适宜种植区域,通过利用灰色关联度和主成分分析方法,结合19个生物气候指标,开展其气候适宜性分析,对涪陵区各乡镇村社的种植气候适宜性进行综合评估.研究发现,等权关联和综合评价模型的结果均支持将涪陵区421个村社的种植气候适宜性划分为3类:Ⅰ类为高适宜区(λ≥0.913),包括新妙、石沱东南部、义和、马鞍南部、龙桥、崇义、江北、南沱西北部、百胜东南部、珍溪东南部、白涛部分地区、荔枝部分地区、江东部分地区;Ⅱ类为中适宜区(0.764≤λ＜0.913),包括增福、石沱西北部、义和北部、李渡、马鞍北部、蔺市北部、荔枝大部分、江东南部、白涛东北部、焦石西南部;Ⅲ类为低适宜区(λ＜0.764),包括龙潭、同乐、青羊、马武、大木、武陵山、罗云、焦石、百胜西北部、珍溪西北部.结果表明,涪陵西北、东北地区是茎瘤芥种植的较佳适宜地.通过研究,为涪陵区茎瘤芥生产的合理布局提供决策参考,有助于促进茎瘤芥产业健康持续发展.
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.
