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

开发了4类土地适宜性分类系统，旨在为农村土地利用规划提供工具。将农用地、宅基地、居民地和生物用地分为农用地、宅基地、生物用地4类，通过四步评判法从所有相关因素中筛选出每一类土地必要且充分的分等因子，然后根据所选因子对每一类土地进行适宜性分类，并对其特征进行检验，建立了区分各土地利用类别分类结果的逻辑，并建立了相应的处理系统，包括估算系数的确定、估计值的推定、分类计算过程以及分类结果在CRT上的分级表示等计算步骤。并在此基础上建立了土地利用规划中各土地类别用地面积与各土地类别用地目标面积的约束体系，最终将各地块区分适宜用途的约束结果转化为具体的农用地整理方案，包括大面积农用地、小农用地、居民区和宜居区，并通过问卷调查进行了农户意见的校核。

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.
