中文摘要:以江西省鄱阳湖及周边经济区耕地为研究对象,将生态位适宜度方法以及克里格插值法引入到多宜性评价研究中,采用加权平均模型和限制因子模型对各评价单元水稻、油菜、棉花和甘薯4种作物的生态适宜度值及限制性生态因子进行了定量分析,结果表明:研究区生态位适宜度值整体较高,最大值达到0.9824,生境条件基本能满足作物的需求;评价结果水稻、油菜和棉花以1、2级为主,所占面积均达到67%以上,甘薯1、2级地占56.9%;综合评价中水稻的适宜性面积最大,达56.1%,棉花次之;限制该地区耕地生产潜力的生态因子主要为:土壤全磷含量、有机质含量、耕作层厚度。该研究结果能直接指导农业生产实践,促进耕地的合理利用与管理。

Abstract:The cultivated land in Poyang Lake region and its surrounding area of Jiangxi province was selected for multi-suitability evaluation by introducing the niche-fitness theory and Kriging method. The means of weighted average and limiting factor models were adopted to quantitative analyze niche-fitness and restrictive factors for rice, rape, cotton and sweet potato. The result shows that the niche-fitness value in the area is higher in general with the peak value reaching 0.9824, and habitat conditions in the region can basically meet the requirements of the crops; The farmlands of rice, rape and cotton are mainly in grade 1 and 2, which account for the area of 67%. Sweet potatoes which are grade 1 and 2 account for 56.9%. In terms of niche-fitness evaluation, area of rice ranks first with the ratio amounting to 56.1%, cotton comes the next; Total phosphorus, OM, and thickness of cultivated layer are the primary niche factors which restrict land productive potential in the area. The results provided direct application in supervision of agricultural production, and promoted reasonable utilization and scientific management of farmland.
