- Abstract
Peanut is an important oil and economic crop in China. The object was to determine the ecological suitability of peanut planting counties in China. 13 indexes of climate and soil were selected. These indices were closely related to peanut production. Chinese county in the administrative divisions was evaluated as investigation u-nit. By using 2005 -2014 climate and soil basic data, the database of ecological suitability evaluation was established through ArcGISplatform. Analytic hierarchy process, fuzzy data method and comprehensive index model were used to obtain the evaluation index. Results led to 4 different grades including the most suitable (0.70 - 0.89], suitable (0.56 - 0.70], sub-suitable (0.42 - 0.56], and unsuitable (0.11 - 0.42]. Among the 4 grades, the suitable grade contained the most evaluation units, and the others were in the order of sub-suitable, most suitable and unsuitable. The grades were zonal distributed. With the most suitable area as the center, suitable and sub-suitable areas were extended to both sides. The areas of the most suitable and suitable grades were mainly distributed in plains, basins, valley areas and oasis, which were concentrated in Guangxi, Shandong, Chongqing, Henan and other 9 provinces. The distribution was consistent with current situation of peanut production in China.
