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

Abstract: 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.
