坐标网格农用地标准样地体系构建方法及应用——以佛山市为例

研究目的:探讨经纬坐标网格法建立标准样地体系的技术路线,以及标准样地体系在农用地分等成果汇总、农用地质量监测与分等成果动态更新、耕地占补平衡、基本农田的划分和保护中的应用。研究方法:对比分析法、实证分析法。研究结果:结合佛山市农用地分等的有关数据对两种方法建立的标准样地成果进行对比分析,利用坐标网格建立标准样地体系可以有效解决现行方法中的不足。

Study on Method of Coordinate Grid in Establishing Standard Plot System of Agricultural Land and its Application:A Case Study of Foshan

The purpose of this study is to study the technical route of establishing standard plot system of agricultural land with coordinates grid method and to find ways to apply the system in integrating the results of agricultural land classification, monitoring the quality of agricultural land, updating the results of classification, achieving "no net loss" of cultivated land, confining and protecting the prime farmland. Methods of comparison and case study were employed. The existing conventional method and the coordinate grid method were used and compared with the data of agricultural land classification in Foshan. The coordinate grid method can overcome some shortages of the existing conventional method.
