Abstract:

The results of cultivated land classification provide a new approach to calculate the integrated productive capacity of cultivated land. Based on the database of cultivated land classification in Bazhou city, in order to evaluate the productive capacity of cultivated land at different levels and to make clear the distribution of the productive capacity, this paper builds up a system for calculating the productive capacity of cultivated land, including natural production potential, accessible production potential, current productivity and actual crop production, and then provides relevant calculation models. Then key protected land regions and priority settlement land regions are divided by applying the results of these calculation modles. A quantitative analysis on comprehensive priorities of various arable lands in each village and town was conducted through these models. By clustering analysis of SPSS, 13 towns are classified into 4 groups, and key protected land regions and priority settlement land regions are rowed up, and each group will have its own development orientation.
