林地细碎化的测度、成因与影响:综述与展望
发布时间：2018-12-13 12:39
【摘要】：对林地细碎化的概念界定、测度方法、主要成因和经济影响进行了梳理。研究结果为:从管理细碎化和空间细碎化两个层面对林地细碎化进行概念界定;采用单项指标、多项指标(地块数量、块均面积、单位面积地块数和地块空间分布)以及综合指标(S指数、J指数和I指数)对林地细碎化进行测度;林地细碎化的成因在于均分承包到户、林地代际继承、人口增长压力以及市场交易机制;林地细碎化具有增加经营模式多样性和促进林地流转的积极作用,但其消极作用十分突出,主要表现在缩减林业生产投入、降低林业生产效率以及减少林业产出和收入等方面。最后,提出了从宏微观相结合的理论视角深入剖析林地细碎化的成因及影响,并强化对其定量分析(测度方法选择、微观定量证据和内生性问题)的研究展望。
[Abstract]:The definition, measurement method, main cause of formation and economic influence of forest land fineness are analyzed. The research results are as follows: the concept of forest land fineness is defined from two aspects of management fineness and spatial fineness; Single index, multiple indexes (number of plots, average area of blocks, number of plots per unit area and spatial distribution of plots) and comprehensive indexes (S index, J index and I index) were used to measure the fragmentation of forest land. The causes of woodland fragmentation are divided equally into households, forestland intergenerational inheritance, population growth pressure and market trading mechanism. The fine fragmentation of forest land can increase the diversity of management mode and promote the circulation of forest land, but its negative effect is very prominent, mainly in the aspects of reducing forestry production input, reducing forestry production efficiency and reducing forestry output and income. Finally, this paper puts forward the research prospect of quantitative analysis (selection of measurement method, microscopic quantitative evidence and endogenous problem) from the perspective of macro and micro theory to deeply analyze the causes and effects of woodland fragmentation.
