耕地面积变化及其影响因素,是当前土地利用研究领域的热点之一,而预测模型的准确性和有效性是对其研究的关键。本文采用BP神经网络模型对江西省2011—2013年耕地面积进行了预测。并采用了灰色关联分析得到了影响江西省耕地面积的主要因素。
The change of cultivated land area and its influencing factors are one of the hot spots in the field of land use research at present. The accuracy and validity of the forecasting model are the keys to its research. In this paper, the prediction of cultivated land area in Jiangxi Province from 2011 to 2013 was carried out by BP neural network model. The main factors affecting the cultivated land area in Jiangxi Province were obtained by using gray relational analysis.
