【Abstract】 This paper discusses how to establish the mathematical model to evaluate apple climate resource in Liaoning Province, and gives the fuzzy mathematical evaluation models of 8 single factors. The formula is where a_i is constant, u_i is variable, c_i is standard value, The formula of comprehensive evaluation is where P is the weighting function. With this method, the apple climate resource in Liaoning Province can be divided three types. They are favorable growing region (≥0.88) such as Dalian, Wafangdian, Jinzhou, Xingcheng; comparatively favorable growing region (0.88>≥0.63)such as Dandong, Anshan, Beizhen, Jianchang; and less favorable growing region(<0.63)such as Kuandian, Benxi, Shenyang and Jianping.更多还原
