- 摘要:
- 划定基本农田既要考虑耕地的自然质量条件，又要考虑耕地与社会经济条件的适宜性，基本农田才能具有长久稳定性。以辽宁省凌源市为例，以LESA方法（land evaluation and site assessment）为指导，结合农用地分等成果，进行耕地质量与立地条件评价分析，并以此为基础划定基本农田。结果表明：LESA体系综合评价结果将凌源市耕地分5级，其中1级、2级和3级耕地自然质量条件较优，与社会经济条件有良好的适宜性，可划定为基本农田，面积为42 697.69 hm2，基本农田保护率达到84.57%。通过分析认为LESA体系继承和沿用了农用地分等成果，可以为农用地定级方法体系研究提供参考。
- Abstract:
- The conditions of farmland natural quality and social economic suitability are considered importantly in planning of the prime farmland, which will make the prime farmland stable permanently. Taking Lingyuan city in Liaoning province as an example, combined with the result of farmland classification, the farmland quality and site conditions are evaluated and analyzed in the direction of LESA method, and the prime farmland is planned on this basis. The results show that the total farmland was divided into five grades by the comprehensive evaluation result of LESA system, the farmlands of grade 1, grade 2 and grade 3 have super natural conditions, and good suitability for social economic conditions, these are planned into the prime farmland, the area is 42 697.69 hm2, the protective rate is 84.57%. The LESA method inherits and adopts the results of farmland classification, and promotes transformation application of the results of farmland classification, it also provides reference for planning the permanently prime farmland scientifically and also for researching the method of farmland grading.
