天山北坡耕地利用转型时空演变及其驱动因素研究OA
Spatio-temporal evolution and driving factors of cultivated land use transition on the northern slope of the Tianshan Mountains
为优化耕地利用格局,摸清耕地利用的发展态势,为天山北坡地区耕地保护提供依据.从空间与功能形态转型两个视角,运用熵值法、空间自相关与OPGD模型等方法,借助ArcGIS空间表达技术,揭示耕地利用转型的时空演变格局及其驱动因素.结果表明:①从时空变化看,2000-2020 年空间形态转型水平逐渐提高、功能形态转型呈平缓波动趋势,高值区由中部核心城市逐步向边缘城市扩散,综合转型指数呈上涨趋势,耕地利用转型格局形成以中部盆地平原、西部伊犁河谷平原为主的高值区与东部山地低值区并存的空间格局;②从空间集聚特征看,空间形态转型呈先减少后增加最后减少的趋势,于2010 年达到峰值,聚集区域由双核逐步向多核发展,功能形态转型呈先升高后再降低最后趋于平缓的态势,聚集区总体位于中部地区;③从驱动因素看,城镇化率、地均固定资产投资与人口密度对耕地利用转型的影响更为突出.综上,天山北坡耕地利用转型结果正逐步向好,但仍存在区域间差异,应利用人口与社会经济因素对转型的驱动作用,促进耕地资源的可持续利用,实现耕地利用优化转型.
To optimize the pattern of cultivated land use,find out the development trend of cultivated land use,and provide a basis for cultivated land protection in the northern slope of the Tianshan Mountains.From the perspectives of spatial and functional morpholog-ical transformation,this paper used the entropy method,spatial autocorrelation and OPGD model to reveal the spatio-temporal evolution pattern and influencing factors of cultivated land use transformation with the help of ArcGIS spatial expression technology.The results showed that:①From the perspective of temporal and spatial changes,from 2000 to 2020,the level of spatial morphological transforma-tion gradually increased,the functional morphological transformation showed a gradual fluctuation trend,the high-value area gradually spread from the central core city to the peripheral city,the comprehensive transformation index showed an upward trend,and the culti-vated land use transformation pattern formed a spatial pattern of coexistence of high-value areas dominated by the central basin plain and the western Ili River Valley Plain and the low-value area of the eastern mountains.② From the perspective of spatial agglomera-tion characteristics,the spatial morphological transformation showed a trend of first decreasing,then increasing,and finally decreasing,reaching its peak in 2010,with the clustering area gradually development from a dual core to a multi-core,and the degree of functional morphological transformation and agglomeration showed a trend of first increasing,then decreasing,and finally tending to level off,and the agglomeration area was generally located in the central region.③From the perspective of driving factors,the impact of urbanization rate,per capita fixed asset investment and population density on the transformation of cultivated land use was more prominent.In conclu-sion,the results of cultivated land use transformation on the northern slope of the Tianshan Mountains are gradually improving,but there are still regional differences,and the driving role of population and socio-economic factors on the transformation should be used to pro-mote the sustainable use of cultivated land resources and realize the optimal transformation of cultivated land use.
