摘　　要：提出了一种作物种植的气候适应性的模糊综合评价方法。作物种植的气候适应性可定义为一定地理环境下,其自然气候条件能满足作物生长所需适宜气候条件的能力。在相同的地理环境下,作物种植的气候适应性因作物种类不同而表现不一,并可表示为该地理环境提供的自然气候条件对不同作物生长所需适宜气候条件的满足程度。作物种植的气候适应性的模糊综合评价包括以下主要步骤:确定影响作物种植的主要气候因子,确定各因子的权重,建立评价因子集并确定气候因子评价标准、建立评价矩阵和计算作物生长气候适应性等。采用该方法对武夷山北坡不同海拔高度柑桔和茶树种植的气候适应性进行了综合评价。This paper presents a framework for assessing climate suitability for crop growing at different geographic locations. For a particular geographic location, climate suitability is defined as its ability to satisfy the climate requirements of particular crops. It is obviously crop-specific and can be expressed as the extent to which the natural climatic conditions satisfy crop growth requirements. Issues that arise when applying the framework to a particular location include selecting major climatic factors that predominantly affect particular crops, weighting importance values of individual factors, setting assessment sets and specifying climatic factor criteria for particular crops, formulating assessment matrixes, and calculating climate suitability for each crop. Based on previously published studies, the assessment of climate suitability for orange (Citrus aurantium) and tea (Camellia sinensis) plants growing at different elevations on the northwards slope of Wuyi Mountain, China illustrates elements of the proposed approach.
