基于土地整治监测监管系统的高标准农田建设状况分析

Analysis on construction of well-facilitated farmland based on land reclamation monitoring and supervision system

为科学分析当前四川省高标准农田建设的空间特征和实施状况,该研究基于农村土地整治监测监管系统,以省域为尺度,县(区)为研究单元,建立建设强度、建设潜力和建设难度为指标的综合评价体系,采用Ward聚类分析的方法,对2012-2015年四川省高标准农田建设状态进行综合分区,并结合既定规划目标与建设成效,对建设状态作定量对比分析,得出以下结论:从分项指标来看,盆地中部丘陵区和盆周山地区建设强度较高,全省建设潜力总体处于中等水平,建设潜力高值区主要位于川中丘陵区、盆周山地区和川西南山地区,成都平原区和川西南山地区建设难度较高;从综合分区来看,全省总体表现为中等偏低建设强度,中等建设潜力和中等偏高的建设难度。成都平原区、盆地丘陵区、盆周山地区和川西南山地区3项指标表现形式分别为中-中低-高、中-中-中、中-中-中和中-中-高;研究表明,目前高标准农田建设状态与规划目标存在一定偏差,且区域差异明显;从区域发展、建设潜力和建设成效多个视角考虑,"十三五"期间高标准农田建设活动在分区上应重点布局在盆地丘陵区和盆周山地区。

In order to scientifically analyze the spatial characteristics and implementation status of well-facilitated farmland construction in Sichuan Province, this research, taking province as measurement scale and county as research unit, built a comprehensive appraisal system with the indicators of construction intensity, potential and difficulty, which was based on rural land reclamation monitoring and supervision system, and aimed to reflect the implementation status of high standard farmland construction. This appraisal system adopted Ward clustering analysis to comprehensively partition the well-facilitated farmland construction status in Sichuan Province during 2012-2015, and conducted a contrastive analysis through combining preset planning goal and construction effect for analyzing the gap between current construction implementation status and planning task. Selection of indicators involved newly increased farmland area, newly increased and improved farmland irrigation area, newly increased and improved farmland waterlogging area, newly increased grain productivity, farmer＇s newly increased annual net income per capita and number of beneficiaries in project areas. For these factors, several aspects were mainly taken into account, such as convenient agricultural operations, enhancing agricultural disaster prevention and mitigation as well as risk resistance ability, and improving agricultural production efficiency, which were to analyze the effect of high standard farmland construction. The conclusions are as follows： from the perspective of single indicator, the construction intensity is higher in the hilly areas of the central basin and the mountain areas surrounding the basin; the construction potential of the whole province is at an intermediate level, while the higher construction potential areas are mainly located in the central Sichuan hilly areas, the mountain areas surrounding the basin and the southwestern Sichuan mountain areas; the construction difficulty is higher in Chengdu Plain and southwestern Sichuan mountain areas; from the perspective of comprehensive zoning, the whole province shows middle-lower construction intensity, intermediate construction potential, and middle-higher construction difficulty. Three indicators of the Chengdu Plain, the hilly areas of the basin, the mountain areas surrounding the basin and the southwestern Sichuan mountain areas perform as medium - medium low- high , medium -medium- medium, medium - medium- medium, as well as medium - medium - high, respectively. Therefore, it suggests that the construction of high standard farmland is suitable for the Chengdu Plain area, especially in the hilly areas of the basin and the mountain areas surrounding the basin, while it should be reduced in the southwest of Sichuan Basin. Research indicates that there exist certain differences between construction status of well-facilitated farmland and planning target currently, especially among different regions. Considering from the regional development, the construction potential and the effect of construction, well-facilitated farmland construction should more focus on the hilly areas of the basin and the mountain areas surrounding the basin during the 13th Five-Year Plan.
