| 摘 要： | 在对400多种作物生态特性调查的基础上,筛选出10多个基本指标因子,建立起具有层次结构的生态适宜性分析指标体系,并提出了单生态因子相对距离和综合生态相对距离计算方法.对11个地区、8种作物的实证分析表明,新建立的生态距离概念具有较强的科学性、实用性、可靠性和广适性,能够较准确和全面地反映作物对各地区的生态适宜性,对种植业结构调整具有重要的指导作用.

| Abstract: | We've selected ten basic index factors and established a set of index system of ecological adaptability of crop.On the basis of investigation of the ecological characteristic of over four hundred crops.The relative ecological gap of crops such as rice,wheat,cotton,soybean,corn,rape,apple and citrus growing in Nanjing,Wuhan,Nanchan,Chendu,Kunming,Quanzhou,Xian,Yinchuan,Beijing,Hearbin and Shengang was calculated and the result showed the concept of ecological gap had scientific spirit,practicality,reliability and extensive application.It can reflect the ecological adaptability of crop.It had important instructive function in plant structure adjustment. |
