【摘要】：森林资源价值评价是森林资源价值核算中包含的一项重要内容。本研究以内蒙古自治区赤峰市旺业甸实验林场为例,提出一种利用3S技术对森林资源价值进行评价的方法。利用GIS分析遥感影像并根据二类调查数据筛选出与林地质量相关的因子,采用层次分析法选取对林地影响较大的因子,以专家评分为支撑,对研究区内样地的林地质量划定等级,建立因子评分标准表,得到不同类型林地指标得分,最后应用收益现值法对研究区内森林资源经营过程中所产生的期间费用、成本费用进行合理可靠的计量,实现对研究区内林地价值评价；对林木资源价值评价采用多边形样地法与TM影像及ZY-3遥感影像相解译相结合,计算得到研究区内的森林蓄积量,采用现行市价法计算得出研究区的林木资产价值量；根据《中华人民共和国林业行业标准LY/T1721-2008森林生态系统服务功能评估规范》对研究区的生态服务价值进行评价。依照上述方法计算得出内蒙古自治区赤峰市旺业甸实验林场当期的森林资源价值为： (1)林地资源价值为6229.5043万元。 (2)林木资源价值为45367.88万元。 (3)生态服务价值为：涵养水源价值：8114.98万元；保育土壤价值：176205.8万元；净化环境的价值：1549.41万元；固碳制氧产生的价值：4524.83万元。本研究通过对林区的实地调查,利用3S技术分析得到研究区森林蓄积量,对研究区林木资源价值存量可靠计量。对林地立地质量根据林地特征选取与环境联系较为紧密的因子进行分析评价,通过相应的评价分数对林地价值进行计算。此种林地质量评价方法较其他方法效率更高,并可以充分反应研究区林地特征。
[Abstract]:The evaluation of forest resource value is an important part of forest resource value accounting. This study takes Wangyedian Experimental Forest Farm in Chifeng City, Inner Mongolia Autonomous region as an example. A method of evaluating forest resource value by using 3s technique was put forward. The factors related to forest land quality were screened by GIS and the factors related to forest land quality were screened according to the second kind of investigation data, and the factors which had a great influence on forest land were selected by AHP. Based on the expert score, the quality of forest land in the study area was classified, and the index score of different types of forest land was obtained by establishing the factor scoring standard table. At last, the method of present value of income is used to measure the period cost and cost of forest resources management in the study area, so as to realize the evaluation of forest land value in the study area. The value of forest resources was evaluated by means of polygonal plot method, TM image and ZY-3 remote sensing image. The forest volume in the study area was calculated, and the value of forest assets in the study area was calculated by using the current market value method. The value of forest ecosystem service in the study area was evaluated according to the Standard of Forestry Industry of the people's Republic of China (LY/T1721-2008). According to the above method, the forest resource value of Wangyiedian Experimental Forest Farm in Chifeng City, Inner Mongolia Autonomous region is calculated as follows:. The value of woodland resources is sixty-two million two hundred and ninety-five thousand and forty-three yuan. The value of forest resources is four hundred and fifty-three million six hundred and seventy-eight thousand and eight hundred yuan. The value of ecological service is: water conservation value: eighty-one million one hundred and forty-nine thousand and eight hundred yuan; soil conservation value: one billion seven hundred and sixty-two million fifty-eight thousand yuan; value of purifying environment: fifteen million four hundred and ninety-four thousand and one hundred yuan; value of oxygen production from carbon sequestration: forty-five million two hundred and forty-eight thousand and three hundred yuan. In this study, the forest volume in the study area was obtained by using the 3s technique through the field investigation of the forest area. The value of forest resources in the study area is measured reliably. The site quality of forest land is analyzed and evaluated according to the characteristics of forest land and the factors closely related to the environment. The evaluation method is more efficient than other methods and can fully reflect the characteristics of forestland in the study area.
