- 摘要:
- 利用GIS技术和熵权理想点排序法构建基本农田决策模型，对乐东黎族自治县的基本农田划定进行研究。结果表明：（1）耕地综合质量评价体系不应仅考虑耕地自然质量，还须兼顾社会经济发展及生物多样性保护需求对耕地的占用；（2）依据14 857块耕地的贴近度大小对其入选基本农田的优先程度进行分区并排序：将贴近度的范围划分为最优区间（0.640 5，0.916 8］，较优区间（0.526 6，0.640 5］，一般区间（0.429 5，0.526 6］，较差区间（0.330 2，0.429 5］和最差区间[0.000 0，0.330 2]，分别占耕地总面积的12.60%，33.33%，29.90%，10.73%，13.45%，最优区间的耕地主要集中分布在滨海佛罗镇和尖峰镇；（3）耕地综合质量评价结果和优先度排序表明，约有13.45%的耕地综合质量较差，不适宜划为基本农田，上级下达的基本农田指标不合理。
- Abstract:
- A decision-making model was built for selecting cultivated land into prime farmland by GIS technology and entropy weighting ideal point. The results revealed that: (1) system of comprehensive quality of cultivated land evaluation should not only consider the quality of cultivated land, but also should take into the cultivated land occupation which aims to meet the socio-economic development and biodiversity protection; (2) priority sort and partition of selecting cultivated land into prime farmland was based on the approach degree calculation, it was divided into optimal interval (0.640 5, 0.916 8］, relatively optimal interval(0.526 6, 0.640 5］, general interval (0.429 5, 0.526 6］, poor range (0.330 2, 0.4295］ and the worst interval [0.000 0, 0.330 2], which accounted for 12.60%, 33.33%, 29.90%, 10.73%, 13.45% of the total cultivated land, respectively; (3)the results of comprehensive quality evaluation and priority sort for cultivated land showed that about 13.45% of cultivated land was in poor range and was unsuitable to be selected as prime farmland, it was not reasonable for higher authorities issued the quantity of prime farmland to Ledong county.
