摘要:
耕地生态安全评价是促进耕地可持续利用的基础。以河北省沧州市为例，基于PSR模型构建区域耕地生态安全评价模型，对沧州市2002—2011年的耕地生态安全状况进行评价，并对其时空分异特征进行了分析。结果表明：（1）从耕地生态安全分区结果来看，沧州市北部地区和南部吴桥的耕地生态安全处于较安全状态，其余地区生态状况不容乐观；（2）2002—2011年，沧州市耕地生态安全水平总体上呈现出先上升后下降趋势，同时具有明显的地域分异性，耕地生态较安全地区大多集中在沧州北部地区；（3）2002—2011年，沧州市中部、西部、东部地区的耕地生态安全水平一直处于较低水平。研究结果可为区域耕地生态安全时空分异研究提供参考借鉴。
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.
