基于 CLUE -S 模型的临潼区基本农田划定研究

摘要

Based on the analysis of existing basic farmland demarcated problems and the principal of CLUE -S model, the paper ex-plored a new method of basic farmland demarcating .The paper made use of CLUE -S model to a case study in Lin Tong District as a research area .The result indicated that on quantity aspect , the difference between simulation and planning value 0.64%.On quality aspect, the part of low quality is slightly decreased , the part of medium quality increased a little , the part of high quality is largely un-changed ,the overall quality has not declined .The conclusion of the study is that this new method of demarcating basic farmland using CLUE-S model is certain scientific and feasible and the method is useful exploration to demarcate basic farmland .%在分析基本农田划定存在的问题和理解CLUE-S模型原理的基础上，探索应用CLUE-S模型进行基本农田划定的新方法，并以西安市临潼区作为研究区进行实证研究。研究结果显示，从数量方面，模拟值与规划值之间的差值率仅有0．64％，从质量方面，低等质量部分面积略有减少，中等质量部分面积有所增加，高等质量部分面积基本没有变化，总体质量没有下降。实现了基本农田划定工作“数量不减少，质量不下降”的要求，说明运用CLUE-S模型进行基本农田划定的新方法具有一定的科学性和可行性，是对基本农田划定新方法的有益探索。
