| 摘 要： | 中国近十年来，随着社会经济的全面发展，城市化进程加快，耕地保护的形势不容乐观，在耕地占补工作中存在“占多补少、占优补劣”的现象。为确保补充耕地面积，提高补充耕地质量，解决国家粮食安全问题，进行农用地分等成果在补充耕地数量质量按等级折算中的应用研究。本文选择湖北省为研究区域，以湖北省农用地自然质量等成果作为研究数据源，采用分层抽样的方法从数据源中选取适量的具有代表性的样本，以这些样本的农用地自然质量等指数和面积数据等相关信息建立基础数据库。在此基础上，开展补充耕地数量质量按等级折算技术方法研究：首先，采用面积加权平均模型计算得到各自然质量等别的平均自然质量等指数；然后，构建按等折算系数计算模型；最终建立各等别间折算关系表。通过本研究得到省级耕地占补平衡等级折算系数表，为严格土地管理和耕地占补平衡的贯彻落实提供理论依据。

| Abstract: | Over the past decades in China, the situation of farmland protection was not optimistic with economic and social overall development and acceleration of urbanization process. Some problems have been existing in the work of farmland requisition- compensation that quantity and quality of compensated land is poorer than that of requisition. Farmland classification was applied to ensure the quantity and quality of supplemental farmland and to solve the problem of national food security. Take Hubei Province as an example, the results of farmland natural quality were taken as data source and established a basic database with farmland natural quality index and areas which were based on the representative samples by stratified sampling method. Based on that research, quantity-quality convert method of supplementary farmland was studied. Average natural quality classification index was calculated by area-weighted mean model, then, conversion index calculation model was established. Finally converted relationship table for each grades of farmland was established, which can obtain the requisition-compensation balance in provincial level. The table provided theoretical basis for strict farmland management and farmland requisition-compensation balance. |
