摘要:

以海南省林地资源为例,开展基于《自然资源分等定级通则》的实践研究工作。创建了不能直接获取数据的分等定级指标解译模型,利用因素法及修正法,构建了海南省林地分定等级的评价方案,明确采用五等五级评价系统。结果表明:海南省国土三调阶段性成果林地1 824.74万hm2,林地分等定级基本单元212.52万个图斑,每个图斑一等一级。实际存在1—4等4个等别;商品林林地788.09万hm2,实际存在1—5级5个级别;公益林林地1 036.65万hm2,实际存在1—5级5个级别。评价结果较好地反映出海南林地实际情况,可为全国林地分等定级工作的规范化、程序化及促进林地资源保护与合理开发利用提供参考。

Abstract:

This paper took the forest land resources in Hainan Province as an example to carry out the practical research work based on the General Rules for Gradation and Classification of Natural Resources for the first time.This paper had created a classification index interpretation model that could not directly obtain data,which constructed an evaluation scheme for the classification of forest land in Hainan Province by the method of factor and correction,and clearly adopted the five grade and five class evaluation system.The results indicated that 18.2474 million hm2 of forest land was the phased achievement of the "The Third Land Survey" project in Hainan Province and there were 2.1252 million basic units for forest land classification and grading,with one grade of each plot.There were actually four grades from 1 to 4;The commercial forest land was 7.8809 million hm2,and there were actually five grades from 1-5;The forest land of public welfare forest was 10.3665 million hm2,and there were actually 1-5 levels.The evaluation results reflected the actual situation of forest land in Hainan,and provided a reference for the standardization and procedure of national forest land classification with the promotion of forest land resources protection and rational development and utilization.

Key words: forestland gradation and classification, commercial forest, public welfare forest, forest land resources, Hainan Province
