Abstract: Quantitative evaluation method is the key to scientifically evaluate the climate quality of agricultural products. Based on the multiple coupling index system, in this paper a quantitative evaluation model of climate quality was established by using the entropy weight valuation method and fuzzy comprehensive evaluation method. The indicators of sunshine, temperature, water, etc. during the growth period of Lycium chinense in east Hexi Corridor were used to evaluate the suitable and extreme disastrous meteorological conditions. The evaluation model of extreme disaster impact was established by grading the main meteorological disaster threshold indexes. The comprehensive evaluation model of climate quality was established by combining the meteorological evaluation and production area evaluation. This method could be used as the basis of quantitatively evaluating the climate quality for L.chinense growth. At the same time, this method could also provide a reference for the quantitative assessment of climatic quality for the growth of similar agricultural products.

Key words: index coupling, climate quality assessment, climate conditions, extreme disaster, Lycium chinense, Hexi Corridor
