Study On Spatial Distribution Characteristics And Influencing Factors Of High-standard Farmland In Xinjiang

High-standard farmland construction is an important means for China to implement the strategy of "hiding grain in the land and hiding grain in technology",which is to further improve rural living standards and promote regional economic development on the basis of ensuring national food security,and is an important measure to further promote the structural reform of the agricultural supply side.To discuss the spatial distribution characteristics and influencing factors of high-standard farmland in Xinjiang,in order to provide decision-making basis and data support for the future construction of high-standard farmland in Xinjiang.First of all,by using spatial analysis methods to reveal the spatial distribution characteristics of high-standard farmland in Xinjiang;secondly,combined with the research method of geographical detectors,the main control factors affecting the construction of high-standard farmland in the two sub-districts of Xinjiang,northern Xinjiang and southern Xinjiang are further clarified;finally,the main influencing factors in the two sub-districts of northern Xinjiang and southern Xinjiang are analyzed in combination with the spatial distribution characteristics of Xinjiang’s high-standard farmland and the main influencing factors under different scales and divisions.Differential construction strategies are proposed for high-standard farmland construction at the county and patch scales,respectively.The results show that:(1)Through the spatial analysis of nuclear density,it is found that there are two significant high-density agglomeration areas in northern Xinjiang and southern Xinjiang,with Tacheng region and Changji Prefecture as the "polar core" in the northern Xinjiang and Aksu region and Kashgar region as the "polar core" in the southern Xinjiang.From the perspective of construction intensity distribution,there is significant spatial agglomeration in the high-intensity areas and high-intensity areas of high-standard farmland construction in various counties and cities in Xinjiang,mainly concentrated in counties and cities in central Xinjiang,and most of the counties and cities around the provincial boundary are low construction intensity counties and cities,and the construction intensity generally shows a distribution pattern of "high in central counties and cities,low in surrounding counties and cities".From the perspective of the distribution of construction potential values,counties and cities with high construction potential are mainly distributed in the western prefectures of Xinjiang’s division,and counties and cities with low construction potential are mainly distributed in the eastern prefectures of Xinjiang’s division.There are 9 counties and cities,accounting for10.23% of all research units,and the average construction potential is 16.08%;there are 33 research units in the high construction potential area,accounting for 37.50% of all research units,and the average construction potential is 62.93%,which is the key development and construction area in the future.(2)From the factor detection results,under the plaque scale,the high-standard farmland construction area in different partitions is strongly affected by economic factors,resource factors and humanistic factors;at the county scale,the high-standard farmland construction area in different partitions is strongly affected by policy factors and resource factors,and overall,agricultural policy is always the dominant driving factor.Judging from the interaction detection results,under the plaque scale,the dominant interaction factors in all partitions are nonlinear enhancement,and the core interaction factors of different partitions are the interaction between traffic location factors and socio-economic factors,indicating that the high-standard farmland construction area in different partitions under the patch scale is strongly affected by traffic location factors and socio-economic factors;at the county scale,only the dominant interaction factors in the whole Xinjiang range are nonlinearly enhanced.However,there are two types of nonlinear enhancement and two-factor enhancement of the dominant interaction factors in the northern and southern Xinjiang regions,and the core interaction factors under different partitions are all policy factors and natural environmental factors,indicating that the high-standard farmland construction area in different sub-districts at the county scale is strongly affected by policy factors and natural resource factors.(3)Combined with the spatial distribution characteristics of high-standard farmland construction intensity and construction potential in Xinjiang county,the 88 counties and cities with high-standard farmland are divided into four construction types: core area,expansion area,maintenance area and adaptation area,and analyze different construction types to put forward feasible development regulation suggestions.Combined with the results of the influence of various factors on the construction area of high-standard farmland in Xinjiang,the main influencing factors in the two sub-districts of southern Xinjiang and northern Xinjiang are analyzed under the two scales of county and plaque,and different construction strategies are proposed for the construction of high-standard farmland in Xinjiang from the county scale to the patch scale in view of the influencing factors of "natural environment,transportation location-social economy and policy regulation".
