【摘要】：通过进行木薯种植适宜性区划研究,为云南省木薯产业的规划布局提供科学依据。根据云南省气候资源特点和木薯对生长环境的要求,分析确定了影响木薯生长分布的适宜性区划指标。结合云南省1∶25万地理信息数据、云南省109个气象站1981—2010年气候资料,选取年极端最低温度、年极端最高温度、年降水量、年平均温度、全年≥10℃活动积温5个气候因子,采用层次分析法求取因子权重,借助地理信息系统(GIS)空间分析技术对区划指标进行细网格推算,推算出无测站地区区划指标的空间分布情况,得出云南省1 km×1 km网格化气候资源空间分布结果,按照最适宜生长区、适宜生长区、次适宜生长区和不适宜生长区对云南省木薯种植进行区域划分,并制作云南省木薯种植区划专题图。区划结果表明:云南省种植木薯潜力很大,可以进一步发展木薯种植产业。
[Abstract]:In order to provide scientific basis for the planning and layout of cassava industry in Yunnan Province, the suitable division of cassava cultivation was studied. According to the characteristics of climatic resources and the requirement of cassava growth environment in Yunnan Province, the suitable regionalization indexes affecting the growth distribution of cassava were analyzed and determined. Based on the geographic information data of 1: 25 million in Yunnan Province, the climatic data of 109 meteorological stations in Yunnan Province from 1981 to 2010 were used to select the annual extreme minimum temperature, the annual extreme maximum temperature, the annual precipitation, and the annual average temperature. Five climatic factors of active accumulated temperature 鈮，
