摘要:

随着区域间的连通性不断增强,土地资源通过商品和服务贸易的间接使用在土地资源利用中扮演着越来越重要的作用,然而目前有关研究仍处于起步阶段,且研究成果十分匮乏。本文利用多区域投入产出模型,从区域贸易的视角核算了中国2012年30个省份和8大区域的隐含土地的使用情况,并进一步分析了隐含土地流动的空间格局特征。结果显示,中国区域间贸易所占据的隐含土地量占全国土地总量的21.39%,各省平均38.54%的土地需求是通过其他省份土地满足的,其中北京、天津和上海80%以上的土地资源消耗来自外省。黑龙江、内蒙古、新疆和河北分别是最大的耕地、林地和牧业用地、渔业用地和建设用地净流出省份(流出量占全省相应土地类型面积的42.26%、27.53%、38.66%和35.28%),而广东、山东和浙江是主要的土地净流入省份。农业土地(耕地、林地、牧业用地及渔业用地)的流动总体上呈现由西向东和由北向南的趋势,东北和西北地区的农业用地流失规模最大,其主要流入华东和华南区域;此外,中国8.43%的耕地、7.47%的林地、6.41%的牧业用地、6.88%的渔业用地和18.35%的建设用地都通过国际贸易供给国外使用。本文的分析为解决中国土地利用与生态保护之间的矛盾及实现土地可持续发展提供可行的思路和理论基础。

Abstract:

With the continuous enhancement of regional connectivity, the indirect land resources use through trade in goods and services plays an increasingly important role in the utilization of land resources. However, relevant research in this field is still in its infancy, and few papers have addressed this issue. This paper, for the first time, uses the multi-region input-output model to calculate the embodied land in the 30 provinces (autonomous regions and municipalities) and 8 regions of China from the perspective of regional trade, and further analyzes the spatial pattern characteristics of embodied land flows. The results show that the amount of embodied land occupied by China's inter-regional trade accounts for 21.39% of the country's total land, and an average of 38.54% of China's provincial land demand is met by land export from other provinces. More than 80% of land consumed by Beijing, Tianjin and Shanghai are from other provinces. Heilongjiang, Inner Mongolia, Xinjiang, and Hebei are the provinces with the largest net exporter of cultivated land, forest and grazing land and aquatic land, fishery land, and construction land, respectively (the outflows account for 42.26%, 27.53%, 38.66% and 35.28% of the corresponding land types in the province); and Guangdong, Shandong and Zhejiang are the main net importer. The flow of agricultural land (cultivated land, forestland, grazing land and aquatic land) mainly generally shows a shift from west to east and from north to south. The regions in northeast and northwest China have the largest scale of agricultural land outflow, mainly into East and South China. In addition, 8.43% of cultivated land, 7.47% of forestland, 6.41% of grazing land, 6.88% of aquatic land and 18.35% of built-up land in China are provided for foreign use through international trade. This paper provides feasible ideas and a theoretical basis for solving the contradiction between land use and ecological protection, and realizing sustainable land use in China.
