我国主要农产品虚拟耕地与资源环境经济要素的时空协调度评价

Spatiotemporal Coordination Evaluation of Virtual Farmland and Resources,Environment and Economic Elements of Major Agricultural Products in China

从时间演变来看,我国主要农产品虚拟耕地(除油料外)与资源、环境、经济要素分别呈现振荡下降、倒"U"型、反转"L"型趋势特征。从空间演变来看,七大行政区域和各省(区、市)主要农产品虚拟耕地与资源环境经济要素协调发展的空间分布特征差异较为突出,但全国主要农产品虚拟耕地与资源环境经济要素的协调发展水平较高,呈持续向好态势。分析我国主要农产品虚拟耕地与资源环境经济要素的协调发展时空演变机理,应当从转变经济发展方式、推动农业供给侧结构性改革、加强农业碳减排力度、建立跨区域合作机制等方面着手。

From the perspective of time evolution, the virtual agricultural land （except for oil） and the resource, environment, and economic factors of China＇s major agricultural products show a tendency of downward oscillation, inverted ＂U＂, and reversed ＂L＂. From the point of view of spatial evolution, the spatial distribution characteristics of the coordinated development of the main agricultural product virtual land and the resource and environment economic elements of the seven major administrative regions and provinces （autonomous regions and municipalities） are quite different. But the level is higher, showing a sustained trend that the coordinated development of virtual agricultural land and resources and environmental economic factors of the major agricultural products in the country. To analyze the temporal and spatial evolution mechanism of the coordinated development of the main agricultural product virtual farmland and resource and environment economic factors in China, it is necessary to proceed from the aspects of transforming the economic growth mode, promoting the structural reform of the agricultural supply side, strengthening the agricultural carbon emission reduction intensity, and establishing a cross-regional cooperation mechanism.
