Abstract: Carya cathayensis, a special forest and fruit product, is suitable to the soil and climate of Zhejiang, but its development has been restricted due to irrational distribution. To provide a scientific basis for distribution and sustainable development of C. cathayensis in Zhejiang Province, geographical information system(GIS) was used to determine the best planting locations. Based on yield and weather relationships as well as biological characteristics,four climate indexes for planting:1)average annual temperature,2) annual rainfall,3)annual duration of sunshine,and 4)favorable days in florescence, were established. Then,these four climatic factors along with factors of slope, aspect, altitude, soil type, and soil texture were used with an analytical hierarchy process to weight nine factors. Next,a comprehensive regional evaluation model of C. cathayensis was established based on applied statistics and GIS techniques. Soil geographical conditions and actual landuse in Zhejiang Province were combined and regions unsuitable for planting were shielded. Planting zones were divided into three grades:optimum,suitable,and unfavorable. Results of the evaluated area for Zhejiang Province indicated that about 26.31% was optimum,33.39% was suitable,and 40.30% was unfavorable.[Ch,1 fig. 3 tab. 17 ref.]
