评估林地基准地价,为林地流转提供参考价格,有利于规范林地使用权交易。基于海南省五指山市林地定级数据,以外业调查样点林地价格为因变量,样点所在定级单元的定级指数为自变量,分地类建立定级指数模型,利用模型计算所有定级单元的林地价格,同一级别的所有林地定级单元价格平均值即为对应级别的基准地价。结果表明,研究区域林地基准地价与林地级别相对应,从1级到5级呈递减趋势,以芒果和荔枝为代表的乔木经济林地基准地价最高,以茶树为代表的灌木经济林地次之,竹林地、短轮伐期用材林地、一般用材林地、一般灌木林地的基准地价依次递减。经济林地价格远高于用材林地,且同一类型的林地价格因树种不同而差异巨大。各级别林地基准地价反映了不同质量林地的价格水平,可以为林地流转提供参考价格,有利于盘活林业资源,推进森林有偿使用,为自然资源保护和合理开发利用提供支撑。

Evaluating the basic price of forest land,which provides reference prices for forest land circulation,is conducive to regulating the transaction of forest land use rights.Based on the forest land classification data of Wuzhishan City,we take the sample price as the dependent variable and the forest land classification index where the sample point is as the independent variable to establish regression model for different forest land types.Then we get the price of all classification units and the average price of each level is the basic price of forest land.The basic price of forest land in the study area corresponds to its level,showing a decreasing trend from level 1 to level 5.The basic price of arbor economic forest land where mango and lychee grows is the highest,followed by shrub economic forest land where tea grows.Bamboo forest land,short rotation timber forest land,general timber forest land,and general shrub forest land decrease sequentially.The basic price of economic forest land is much higher than timber forest land.The prices of the same type of forest land vary greatly due to different tree species.The basic price reflects the level of different quality forest land,which can provide reference for forest land circulation.The research results are beneficial for revitalizing forestry resources,promoting compensated use of forests,and providing support for protection and rational utilization of natural resource.
