- Abstract:
-
Evaluation on cultivated land ecological security is the basic of promoting the sustainable utilization of cultivated land. Taking Cangzhou City in Hebei Province as the example, based on PSR model to constrict the regional cultivated land ecological security evaluation model, we evaluated the state of cultivated land ecological security and quantitatively analyzed the different features of time and space from 2002 to 2011. The findings suggest the followings. First, cultivated land ecological security is in the safe state in northern and southern Wuqiao in Cangzhou City, but the other regions are not optimistic. Second, from 2002 to 2011, cultivated land ecological security level in Cangzhou City had a trend which went up and then went down and had obvious regional differentiation, the region of cultivated land ecological security mostly concentrated in northern Cangzhou City. Third, from 2002 to 2011, cultivated land ecological security level had been in a low state in the central, western and eastern parts of Cangzhou City. The results of the research can provide reference for time and space differentiation study on cultivated land ecological security.
