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

建立了4类土地类型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。4类土地分别是农业用地、业余用地、居民用地和生物用地。从所有相关因子中，通过四步审查程序筛选出各土地类别的必要和充分分类因子集，然后根据所选因子对各土地类别进行适宜性分类，并对其特征进行审查。然后，开发了区分地块合理利用的逻辑，综合了各个土地利用类别的分类结果，并对其处理系统进行了开发和检验，包括估算系数的确定、估计值的推定、分类计算过程和结果在CRT上的图形显示等计算程序。针对上述结果，制定并采用了土地利用规划中各用地类别分类用地面积对各用地类别反对用地面积的限制制度。最后，将各地块划分出适宜用途的限定结果转化为具体的农地整理方案，该方案由大型农业用地、小型业余农场用地、居住区用地和美化区用地组成，并通过向郊区询问农户意见进行审核。

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.
