四川省中江县高标准基本农田建设时序与模式分区

针对高标准基本农田建设中集中连片、设施配套、生态良好等要求,以中江县为例,从耕地的自然禀赋、基础设施与工程施工条件、社会与经济可接受性3方面选取12个指标,运用理想解逼近法和限制因素组合法,对西南丘陵区高标准基本农田建设做出时序安排与模式分区。结果表明,中江县高标准基本农田建设时序安排上近、中、远期整治区的面积分别占总耕地面积的19.28%、37.86%、43.86%;中江县高标准基本农田建设可划分为3个模式区,即坡度限制因素区、农田水利基础设施重点建设区和农田道路重点建设区,各区所占比例分别为41.34%、31.53%和27.13%。研究方法可为县域土地整治规划和高标准基本农田建设提供科学依据。

Time sequence and mode partition of high-standard prime farmland construction in Zhongjiang county, Sichuan province

Aimed at the construction requirements with concentration, fully supported facilities and friendly environment, taking Zhongjiang county as study area, a reasonable way in mapping out the time sequence and construction mode of high-standard prime farmland was investigated. And the time sequence and mode partition of high-standard prime farmland construction were determined by the technique for order preference by similarity to ideal solution (TOPSIS) and limiting factors analysis methods. Considering the natural endowments, infrastructure and construction conditions and economic and social affordability, 12 indexes were selected and analyzed. The results showed that high-standard prime farmland in Zhongjiang county could be divided to near-, mid- and long-term construction, and their area proportion of near, mid and long-term construction was 19.28%, 37.86% and 43.86%, respectively. Meanwhile, high-standard prime farmland in Zhongjiang county could be divided to three construction modes, namely slope modification construction mode, irrigation works construction mode and field roads construction mode, and their area proportion was 41.34%, 31.53% and 27.13%, respectively. This research provides a scientific basis for consolidation plan and construction programs of high-standard prime farmland in counties.
