- 摘要:
- 针对划定基本农田质量、数量的多重要求，以红兴隆垦区二九一农场为例，从耕地的自然质量条件、区位条件、耕地周围影响因素3个层面建立了一般农田划入基本农田的指标体系，并借助GIS技术提取各评价指标的空间属性数据；运用等间隔赋值法进行耕地的质量和区位的优劣排序；建立一种以耕地质量评价为基础的“按质定量”的基本农田划定方法。结果表明：二九一农场优质耕地所占比重较小，且分布较为分散。若使其基本农田保护率达到国家规定的指标，评价分值≥70分的耕地区域是理想的基本农田保护区。实证研究表明此种方法可以减少基本农田划定中人为因素的干扰，使得基本农田的划定更为科学合理。
- Abstract:
- According to the basic farmland demarcation with the requirement of quality and quantity, 291 farm of red booming land reclamation area was taken as an example, index system of identifying the general farmland as the basic farmland was established based on three level factors of the cultivated land natural quality conditions, location, and cultivated land surrounding, and retrieved space attribute data of individual evaluation index with the aid of GIS technology. By using interval assignment method for cultivated land quality and sort of advantage and disadvantage location, a basic farmland demarcation method of cultivated land quality evaluation based on the foundation responsible for the quantity was set up. The results showed that the proportion of high quality land in 291 farm was low, and distribution was more dispersed. If the basic farmland protection ratio meets the state index, cultivated land area scored 70 points or more was the ideal basic farmland protection area. The empirical research showed that this method can reduce human interference for the basic farmland demarcation, and make the designation of the basic farmland more scientific and reasonable.
