摘    要:本文在分析农用土地分等、定级目的基础上,以广州市天河区为例探讨了大城市郊区农用土地定级的思路、方法、对象及其参评因素因子体系等,并进行了实际研究。结果表明:大城市郊区农用土地定级:(1)除耕地(主要为菜地)外,定级对象还应包括园地、林地等农用土地类型;(2) 应采用将土地相对稳定和易变两大类因素因子影响作用同时评定并进行综合的方法,而不宜采用对土地分等指数进行易变因素因子订正得到定级指数的做法;(3) 宜采用多种方法并相互比较和印证,从而提高定级结果的精确性。

关 键 词:大城市郊区  农用土地定级  模糊综合评判  广州市

Moreover, the actual research was carried out. The results showed that: the agricultural land gradating in metropolitan suburban (1) should take the fruit land and forestry land as the evaluated object, besides the cultivated land (mainly the vegetable land); (2) should accept the method that evaluates and gathers the influence and function of the relatively stable and variable factors and elements of the land simultaneously, but the method that revises the ranking index further according to the variable factors and elements of the land; and (3) should be carried out by divers ways, and compare and confirm mutually to improve the accuracy of gradation result.
