基于景观格局分析的昌黎县基本农田分区

Primary Farmland Regionalizati on in Changli County Based on Analysis of Landscape Pattern

为了反映基本农田景观特征,更好地完成基本农田保护工作,采用景观格局指数和基本农田综合景观指数的方法,对昌黎县基本农田从景观格局角度（即总量、形态、分布和主导类型等4方面）进行分析研究.结果表明：昌黎县各乡镇可划分为4个基本农田景观等级,1～4级的基本农田总量分别为16 897.21 hm2、24 199.93 hm2、11 609.06 hm2和2 212.77 hm2,其占全县基本农田面积的比例分别为30.77％、44.06％、21.14％和4.03％.结论：对处于不同级别的乡镇应采用不同的基本农田优化和保护措施.

In order to reflect the landscape characteristics of primary cultivated land,and to protect primary cultivated land better,the author analyzed primary cultivated land in Changli County based on landscape patterns(such characteristic included that of the amount,spatial form,distribution and the dominant types of primary cultivated land),by using landscape pattern index and integrated landscape index values of primary cultivated land.The results showed that villages and towns in Changli County were divided into four landscape levels.The amount of primary cultivated land in four levels areas was respectively 16 897.21hm2,24 199.93hm2,11 609.06hm2 and 2 212.77hm2,accounting for 30.77%,44.06%,21.14%and 4.03%respectively of the total farmland area in Changli County.The conclusion is that we should put forward the corresponding suggestions for optimization and protection of primary cultivated land at different levels of townships.
