摘要:

建设高标准基本农田是保证中国粮食安全的重要举措,具有重要现实意义。选取重庆市垫江县为研究区,结合农用地质量分等、土地利用变更等多元数据,利用生态位(Niche)、局部莫兰指数(Local Moran’s I)、多元约束(Multi-constraints)方法进行高标准基本农田建设适宜性评价与区位选址,以期为垫江县及类似丘陵地区土地整治工作提供可参考的科学依据。研究表明:①评价指标空间离散性不一,地块连片度、田间道路通达度和地块到居民点距离变异性最强,成为高标准基本农田建设需要适当考虑的关键因子;②区位要素与综合适宜度空间分异明显,自然禀赋、基础设施和社会条件的适宜性表现为西部平坝、北部丘陵和中部河谷地带较高,而南部及“三山”(明月山、南华山和黄草山)地带较低,生态环境的适宜性空间格局反之,高标准基本农田综合适宜性格局亦表现为西部、北部和中部较强而南部较低的态势;③建设选址结果占基本农田的28.76%,同政府实际划定结果相比多出14.48%,说明垫江县高标准基本农田建设条件较好。上述研究表明,基于生态位、空间自相关和多元约束方法,能够较好地指导高标准基本农田建设与选址工作。

Abstract:

For national grain safety it is necessary to construct high standard basic farmland. Here we chose Dianjiang County in Chongqing as the study area and used farmland quality grade data and land use change data to evaluate construction suitability and construction area using Niche modeling, Local Moran’s I and multiple constraints methods. We found that the discreteness of the location index is diverse, and among them, variation in the contiguous degree of land, accessibility of field road and distance between land and settlements are the most obvious and primary factors in high standard basic farmland. Pattern factors and the comprehensive location are diverse in space. The suitability in west Pingba area, north hilly area and river valley areas are higher, and lower in the southern area and three mountains area. However, the suitability pattern of the ecological environment is contrary. The comprehensive suitability of high quality standard farmland also indicates the pattern, which is stronger in the west, north and middle area. The constructing results field site occupies 28.76%, 14.48% more than government results have indicated. This tells us that the construction of high standard basic farmland in Dianjiang is better than others. To sum up, the method based on Niche, spatial autocorrelation and multi-constraints can support the work of high standard basic farmland.
