本文以福建、江西、湖南、四川、浙江、广西、河南、山东、辽宁等9省份18个县(市、区)2420户农户调查数据为基础,运用定量分析方法,衡量林地地块数量、面积、距离和细碎化综合指数等,分析集体林权制度改革前后的农户林地细碎化程度及其空间特征。结果表明,以S指数衡量,中国集体林地细碎化程度已达到0.41,且空间分布由高到低依次顺序是浙江、江西、湖南、辽宁、四川、福建、广西和山东,自然地理因素是影响林地细碎化空间差异的重要因素。
Based on the survey data of 2420 households in 18 counties (cities, districts) of 9 provinces including Fujian, Jiangxi, Hunan, Sichuan, Zhejiang, Guangxi, Henan, Shandong and Liaoning, the paper uses quantitative analysis method to measure the quantity and area of forest land, , Distance and fragmentation comprehensive index and so on, analyzes the extent of fragmentation of forest land and its spatial characteristics before and after the reform of collective forest tenure system. The results showed that the degree of fragmentation of the collective forest land in China reached 0.41 by the S index, and the order of spatial distribution from high to low was Zhejiang, Jiangxi, Hunan, Liaoning, Sichuan, Fujian, Guangxi and Shandong. The natural geographical factors affected the forest land An important factor in the fragmentation of space.
