【摘要】为了实现对牧草适应性的定量化研究,以草原综合顺序分类法、牧草生长的气候适宜度、牧草种或品种的生物学特性理论为依据,确定了牧草适应性影响因子,并采用模糊逻辑和层次分析法建立了其隶属函数;在地理信息系统(GIS)平台的支持下,建立了数据库并形成了牧草适应性的GIS产品。通过这些研究,得出了牧草适应性的定量化定义。更多还原

【Abstract】 This study mainly focus on quantitative part of forage adaptability(FA).The main factors affecting FA were ascertained according to theories of grassland integrative sequence taxonomy,the eco-climate suitability degree to forage growth and forage biological traits.And membership functions of these factors were built based on fuzzy logic and Analytic Hierarchy Process(AHP).Then,these results were combined with GIS through computer programs.Finally,the definition for FA was gained based on the former research.更多还原
