| 摘 要： | 以农用地分等成果为基础进行耕地评价与立地条件分析研究，在土地评价领域推进农用地分等成果转化应用。该文以辽宁省凌源市为例，充分利用农用地分等成果，借鉴美国LESA（land evaluation and site assessment）思想，对研究区分别进行耕地质量评价和立地条件分析，并建立凌源市耕地质量评价与立地条件分析体系。该体系评价结果将凌源市耕地分为8级，其中1和2级耕地属于自然质量条件和立地条件较优的耕地，3～5级耕地属于自然质量条件尚可，受立地条件影响差异较大的耕地，7和8级耕地属于自然质量条件较差，无任何立地条件优势的耕地。以农用地分等成果为基础建立土地评价与立地条件分析体系是切实可行的，同时在该体系中要因地制宜的选取耕地立地条件因素。

| Abstract: | The purpose of this paper is to conduct research of land evaluation and site assessment based on agricultural land classification results and promote its transformation application in land evaluation field. Taking Lingyuan city in Liaoning province as an example, making full use of agricultural land classification results, the farmland quality and site condition were evaluated separately based LESA method, and the system of farmland evaluation and site assessment was established. The results showed that the total farmland in Lingyuan city was divided into eight grades in this system, the farmland of grade 1-2 had the best natural and site conditions, the farmland of grade 3-5 had normal natural conditions, but being influenced large differently by site conditions, the farmland of grade 6-8 had poor natural conditions and bad site conditions. It is concluded that the system of land evaluation and site assessment established on the basis of results of agricultural land classification is feasible, and the selection of site factors should accords to the native condition. |
