摘 要:为探究中国森林资源建设与保护的时空演变规律,以及发展的过程中是否存在空间关联和集聚效应,明确中国森林资源建设与保护的关键障碍因子,该研究运用熵值法测算中国森林资源建设与保护的综合评价指数,运用Moran指数检验中国森林资源建设与保护水平的空间关联效应和空间集聚效应,运用障碍度模型确定影响中国森林资源建设与保护的关键障碍因子。研究结果表明,中国森林资源建设与保护水平综合得分从2011年的0.3521上升至2020年的0.7050,并且表现出明显的阶段性特征;全局Moran指数均大于0,2015—2016、2018—2020年通过10%显著性检验;局部Moran指数2020年在10%显著水平下只有黑龙江、吉林呈现“高-高”集聚。起源结构、林龄结构、人均林地面积和森林火灾次数是影响中国森林资源建设与保护的主要障碍因子。2011—2020年中国森林资源建设与保护整体呈上升趋势,存在明显空间正向自相关,多数省份空间关系并不显著,但集聚程度随时间演进不断增强。森林建设水平是中国森林资源建设与保护的主要障碍因素,为此,提出了推动中国森林资源建设与保护的对策建议。In order to explore the spatial-temporal evolution of forest resources construction and protection in China,whether there are spatial correlation and agglomeration effects in the process of development,and identify the key obstacles to forest resources construction and protection in China,the entropy method was used to calculate the comprehensive evaluation index of forest resources construction and protection in China,the Moran index was used to test the spatial correlation effect and spatial agglomeration effect of forest resources construction and protection level in China,and the obstacle model was used to determine the key obstacle factors affecting the construction and protection of forest resources in China.The results showed that:the comprehensive score of China's forest resources construction and protection level increased from 0.3521 in 2011 to 0.7050 in 2020,and showed obvious stage characteristics.The global Moran index was all greater than 0 and passed the 10%significance test during 2015-2016 and 2018-2020.The local Moran index showed“high-high”agglomeration only in Heilongjiang and Jilin at the 10%significant level in 2020.Origin structure,forest age structure,per capita forestland area,and forest fire frequency were the main obstacles affecting the construction and protection of forest resources in China.From 2011 to 2020,the construction and protection of forest resources in China showed an upward trend.There was obvious spatial positive autocorrelation,and the spatial relationship of most provinces was not significant,but the degree of agglomeration increased with the evolution of time.The level of forest construction is the main obstacle to the construction and protection of forest resources in China.Based on this,some countermeasures and suggestions are put forward to promote the construction and protection of forest resources in China.
