基于农用地分等的农地质量分析——以河北省廊坊市广阳区为例

目的]为全面提高耕地质量提供科学指导。方法]针对河北省廊坊市广阳区耕地情况,通过对影响其耕地质量因素的筛选分析,剖析其耕地的质量状况以及存在的问题,提出该区农用地合理利用建议。结果]通过对影响其土地质量自然性状表土质地、土体构型、有效土层厚度、灌溉状况等5个分等因素进行调查分析,根据农用地分等规程中农用地自然质量分的计算程序,得到各单元的自然质量分,通过对自然质量分的分段,将广阳区划分为3个区域,获得细化到村级土地质量状况的分析。结论]广阳区北临北京市,东连廊坊市,具有极高的区位优势,应着眼于满足城市对农产品的需求,通过合理作物布局,积极发展在城市有广阔市场的作物品种。

Analysis on Farmland Quantity Based on Farmland Grading

Objective] The purpose of this study was to provide scientific directions for enhancing farmland quality thoroughly.Method] Aiming to farmland condition of Guangyang district in Langfang city of Hebei province,the its quality condition of farmland and existing problems were analyzed through screening analysis on the factors influencing its farmland quality so as to put forward the suggestions of utilizing farmland reasonably in this district.Result] According to the calculation program of natural quality score of farmland in its grading practices,the natural quality scores of various units were obtained through investigating and analyzing 5 grading factors influencing the natural character of land quality,such as texture of surface soil,profile form of soil body,thickness of available soil layer and irrigation condition.Through segmenting natural quality scores,Guangyang district was divided into 3 regions and the analysis on the quality condition of land specified to village grade was obtained.Conclusion] Guangyang district was south to Beijing city and connected with Langfang city in the east.It had great regional advantage.The attention should be paid to satisfying the need for agricultural products of urban and the crop varieties with broad market in urban should be developed through distributing crops reasonably.
