摘  要：
在我国生态文明建设不断向前推进的背景下,维护和改善森林生态系统的整体性和系统性具有十分重要的意义。文章基于2000-2018年京津冀38个样本县的卫星影像数据和社会经济统计数据,对森林破碎化程度进行了定量测算,并对森林破碎化的社会经济影响因素进行了实证分析。研究发现,人均GDP对京津冀样本县森林破碎化程度的影响呈倒"U"型,即在人均GDP较低的发展阶段,人均GDP增长加剧了森林破碎化程度;随着人均GDP的提高,在经历拐点后人均GDP增长则有助于降低森林破碎化程度。此外,退耕还林工程对森林破碎化的影响为负,退耕还林工程的实施有助于降低森林破碎化的程度。城镇化比率、农村人均用电量、人均粮食播种面积以及人口密度等变量对样本地区森林破碎化程度的影响不显著。在此基础上,提出了减缓森林破碎化的政策启示,以推动京津冀区域可持续发展。文章的创新之处在于:一是从理论分析的角度丰富了森林破碎化影响因素的研究成果;二是基于人文地理与林业经济交叉学科视角,利用县域层面数据和计量回归模型在提高研究结论准确性的同时,为促进社会经济与森林生态的协调发展提供了一定的实践指导。

摘  要：
With the continuous strengthening of ecological civilization construction in China, it is of great significance to maintain and improve forest ecosystem integrity. Based on the remote sensing image data and socio-economic statistical data of 38 sample counties in the Beijing-Tianjin-Hebei region, this paper measures the level of forest fragmentation and empirically analyzes the socio-economic determinants of forest fragmentation. The results show that the impact of per capita GDP on forest fragmentation in Beijing-Tianjin-Hebei sample counties presents an inverted "U" shape. In the initial development stage with low per capita GDP, per capita GDP enhances forest fragmentation. With the increase of per capita GDP, per capita GDP helps to slow down the forest fragmentation after the inflection point. In addition, the impact of the SLCP on forest fragmentation is negative, while the impact of urbanization on forest fragmentation is positive. The impact of urbanization rate, electricity consumption per capita, grain sown area per capita and population density on forest fragmentation is insignificant. On this basis, the paper puts forward the policy implications to slow down the forest fragmentation, which can help promote the coordinated development of socio-economy and forest ecology in Beijing-Tianjin-Hebei and to promote the sustainable development of this region. The innovations of this paper are as follows: First, it enriches the theoretical research on the impact factors of forest fragmentation. Second, based on the interdisciplinary perspective of human geography and forestry economics, we use county level data and econometric regression model to improve the accuracy of the research, and provide some practical guidance for promoting the coordinated development of socioeconomy and forest ecology.
