摘要
在分析了400多种作物的生态适应性资料的基础上,构建了作物生态适宜性评价指标体系。根据生态因子的限制原理,在生态因子的稀缺性指数的基础上,提出了作物生态适宜性分析的变动赋权原理和方法,克服了传统主观赋权法的不足,形成了较为系统的作物地域生态适宜性评价分析方法。实例分析结果表明,该方法评价结果符合实际。
Based on the analysis of the ecological adaptability of about 400 crops, an evaluation index system was established. On the basis of limitation law of ecological factors, variable weight principle and method were introduced into establishing a systemic approach of crop ecological adaptability evaluation to avoid the disadvantages induced by subjective weighting method. Case study showed that the evaluation results agreed with the fact of present cropping structure.
