Systematic analysis of agro-ecoclimatic resources in Gansu Province
摘要
Abstract
Based on the over years data from 86 meteorological stations in Gansu Province, the agro-ecoclimatic esources in this province was systematically analyzed. Resource indices Cr, efficiency indices Ce and utilization coefficient K were calculated by using the dynamic models of agro-ecoclimatic suitability degree. According to the average monthly efficiency indices Ce, the agro-ecoclimatic resources were divided into 7 types and 3 subtypes by fuzzy cluster. The potentiality matching condition and utility degree of agro-ecoclimatic resources showed the evident characteristic of spatial differentiation. Generally, the south was superior to the north, and the east was superior to the west in terms of these parameters, with the type of South Gansu Mountain much better than that of Hexi Corridor. Some suggestions about the exploitation and utilization of the agro-ecoclimatic resources in Gansu province were proposed.关键词
