摘要
土地资源是制约经济增长和改善人民生活最严重的＂瓶颈＂,为了让有限的土地资源得到充分、合理的利用,系统开展区域土地资源空间优化配置的研究是一项十分迫切的任务,而进行经济林用地适宜性评价是土地资源优化配置的重要内容,对制定土地利用规划、进行林业结构调整、保护区域生态环境、实现区域资源环境可持续发展具有重要意义。
The paper took forest in Poyang Lake region for case to study the suitability evaluation by introducing the Nichefitness theory and Kriging method. The weight average model was used to quantitative analysis the nichefitness and restrictive factors for growth of Camellia oleifera and Cunninghamia lanceolata. The results show that the nichefitness value in the region is in medium and the suitability for growth of economy forests is strong. The ratio of land suitability in grade 1 and 2 for Camellia oleifera planting to forest land is account for 79.51% , grade 2 and 3 for Cunninghamia lanceolata account for 70.07%. In terms of comprehensive suitability evaluation result, Camellia oleifera suitable area ranks first with the ratio amounting to 71.23%. Total phosphorus and organic matter content are the primary limited factors to restrict the economic forest growth in the region. The results can apply to guide economic forestry production, to promote the forest land reasonable utilization and management.
