Research on the land suitability classification system for rational development of rural land-use planning

建立了4个地类类型的土地适宜性分类体系，旨在作为编制农村土地利用规划的工具。以农业用地、休闲用地、居民地和生物用地4个土地类型为研究对象，通过4步检验程序，从所有相关因子中筛选出各土地类型的分类因子集，并在此基础上对各土地类型进行适宜性分类，分析了各土地类型的适宜性特征。开发了综合各土地利用类型分类结果的地块合理使用判别逻辑，并开发了包括估算系数确定、估算值推定、分类计算过程和CRT图形显示等计算步骤的处理系统。最后，将各地块适宜用途区分的约束结果转化为具体的农地整理方案，包括大面积农业用地、小面积休闲农业用地、居住区和生活区，并由农民的意见通过调查委员会进行检查。

4 land categories type land suitability classification system was developped aiming tobe used as a tool to plan rural land use plan. 4 land categories are agricultural farm land, hoby use farm land, resident land and living thing land.Selection of necessary and sufficient set of clasification factors of each land category was done through four step examine procedure from all relevant factors, then, suitability classification for each land category was done based on each selected factors, and its characteristics are examined.Then, the logic to distinguish proper use of plot to synthesize clasiffied results of each land use category was developed and its processing system incruding the computing procedures such as determination of estimation coefficient, presumption of estimate value, computing process of classification and grafic presentation of results on CRT was also developed and examied. and also astriction system of classified land area of each land category to objected area of each land category of land use plan was developped and adopted to the result above.Finally, such astricated result of distinguished suitable use of each plots are turned to concrete farm land consolidation plan which consist of large size plot for agriculture, small farm for hobby farming, residental area and amenity area, and checked by farmaes opinions through enquate surbey.
