摘要
本文从剑麻种植的气侯角度出发,选取了6个气候因子,定出了5个评价等级指标。分别构造了各个因子各个等级的隶属函数,采用Fuzzy综合评判方法,对中国南部5省(区)的131个代表点的剑麻种植气候环境质量进行综合评判,为我国南部利用气候优势合理种植剑麻提供了客观的科学依据。
According to the climate conditions for sisal hemp planting, six climate factors and five grade indexes are chosen for appraisal of eco-climate region. The subordinate function of each factor in different grades is formed respectively. The climate conditions of sisal hemp planting in 131 representative points of five provinces in South China (Guangdong, Guangxi, Fujian, Yunnan and Ha inan) is appraised by fuzzy comprehensive appraisal method. Five grades of regions are delineated: the favourable planting region, the suitable planting region, the plantable region, the unsuitable planting region and the unplantable region. The result of the appraisal will provide an objective scientific basis for rational sisal hemp planting in South China.
