%X This article,chooses Datong city and seven counties under its jurisdiction in Shanxi province locating at the edge of the Loess Plateau and being eco-geographical sensitive region as research objects according to the long time climate survey data from 1971 to 2000, and based on the agriculture eco-climate amenity degree dynamic model established by GU Heng-yue and AI Nan-shan, and several vegetation experiments, tentatively points out eco-climate amenity degree attribution function; using which, calculates resource index,efficiency index and utilization coefficient by areas, and creatively concludes that temperature and precipitation amenity degree of Datong city and the other seven counties appear "Λ-shaped" tendency, and the peak value occurs in summer; while sunshine amenity degree of them appears "V-shaped" tendency, and the time of resource being abundant is longer, and the low value of resource amenity appears in July of every year. According to fuzzy clustering, the average efficiency index of every region by months, demarcates three types of agriculture eco-climate which are appraised respectively. The results show that the agriculture eco-climate resources of Guangling,Datong and Zuoyun counties are better, the value of Ce is between 1.5 and 2.5, especially the configuration of water and temperature resources is reasonable and the sunshine time is opulent; those of Tianzhen,Lingqiu and Yanggao counties are common, the value of Ce is between 1.0 and 1.5, water and temperature are synchronous, but the sunshine time is shorter than the former; and those of Datong city and Hunyuan county are the poorest, the value of Ce is less than 0.5, especially the sunshine time appears short throughout the year.
