基于景观格局指数的基本农田保护区集中连片性研究——以济南市历城区为例

耕地与基本农田保护是我国土地管理、土地利用规划的重要内容。新一轮土地利用总体规划修编及数据库建设中要求基本农田调整布局更加集中连片。该文应用景观格局指数,研究了济南市历城区基本农田保护区规划调整中集中连片性的变化。结果表明,除保护区图斑面积标准差外,图斑平均面积、图斑面积变异系数、图斑边界密度、最大斑块指数、平均欧式邻近距离5项指标均表明,规划调整后基本农田保护区布局上更加集中连片。为基本农田保护区布局的集中连片性判断提供了简便易行的方法。

Study on Integrity and Continuity of Basic Farmland Protection Based on Landscape Pattern Index---Setting Licheng District in Jinan City as an Example

Farmland and basic farmland protection are important contents of land management and land use planning. Integrity and connectivity of distribution pattern of basic farmland should be adjusted in the new land use planning and database construction. By using landscape index, the integrity and connectivity of basic farmland protection zone have been studied in Licheng district of Jinan city. It is showed that, except patch area standard deviation, the other indexes, such as average patch area, patch area variation coefficient, patch edge density, largest patch index, and mean euclidean nearest-neighbor all indicate more connectivity of basic farmland protection zone after layout adjustment. It is simple and easy method for identifying the integrity and connectivity of basic farmland protection zone.
