Taking Anqiu City, Shandong Province, China as an example, dynamic change of cultivated land resources of Anqiu City is analyzed from the aspects of the quantitative change of cultivated land resources, the structural change of cultivated land resources, and the regional differences of cultivated land change. Based on the land demand prediction of grain demand, the land demand prediction of economic crop production, and the land requirement goal, factors affecting the requirement goals of cultivated land resources are discussed. Linear Prediction Model and Polynomial Forecasting Model are used to discuss the goal forecast of cultivated land resources based on time series, which provides basis for decision making of land use in Anqiu City within planning... |
