【摘要】：林地是国家重要的自然资源和战略资源,是森林赖以生存和发展的根基。开展立地分类与质量评价,对于实现适地适树地科学造林、营林、育林具有重要指导作用,对于科学管理林地资源,推进生态文明和美丽中国建设具有重要现实意义。本文基于浙江省森林资源连续清查体系,利用固定样地立地因子调查数据、林木生长量连续测定数据等,对浙江省立地分类与质量评价体系进行了探讨,主要有以下几方面内容：(1)根据山地丘陵和平原林地立地主导因子不同,分别采用逐步回归分析法、定性与定量分析相结合法等,筛选立地分类主导因子,建立了浙江省立地分类系统,将全省划分为2个立地区,9个立地类型区,建立20个立地类型组,52个立地类型。(2)根据建立的立地分类系统,采用数量化方法和层次分析法,分别对每个立地单元进行定量化评分,评定各立地单元的立地质量等级,建立了立地质量评价体系。全省共分262个立地单元,分别评为一等地、二等地、三等地、四等地、五等地5个质量等级。(3)根据2012年浙江省森林资源复位调查样地数据,利用构建的立地分类系统和评价体系,采用系统抽样统计方法和地统计Kriging插值法,评价了全省林地的立地质量,制作了立地质量分布图。(4)根据森林资源连续清查数据特点,采用异速生长模型法,获取了样木、样地水平生物量和间隔期内生物量年均生长量数据；在此基础上,建立了立地因子与生物量生长量间的立地质量数量化评价模型。
[Abstract]:Forest land is the important natural resources and strategic resources of the country, and it is the foundation for the survival and development of the forest. Developing site classification and quality evaluation plays an important role in guiding scientific afforestation, silviculture and afforestation, and has important practical significance for scientific management of forest resources and promoting the construction of ecological civilization and beautiful China. The forest resources in Zhejiang Province Based on continuous inventory system, using fixed sample survey data of site factors and growth in continuous determination of data of Zhejiang Province, site classification and quality evaluation system were discussed as follows: (1) according to the site of Hilly and plain forest in different leading factors, respectively step by step the regression analysis method, qualitative and quantitative analysis method of combining, selection of site classification is the dominant factor, Zhejiang Province set up site classification system, the province will be divided into 2 regions, 9 site type District, building 20 site type group, 52 site types. (2) according to the established site classification system, we use quantitative method and analytic hierarchy process to quantitatively mark each site unit, evaluate site quality level of each site unit, and establish site quality evaluation system. The whole province is divided into 262 site units, which are evaluated for 5 quality grades in the first class, two, three, four, and five, respectively. (3) according to the data of forest resetting survey data in Zhejiang province in 2012, using site classification system and evaluation system, using systematic sampling statistics method and geostatistics Kriging interpolation method, we evaluated the site quality of forest land in the whole province, and made the site quality distribution map. (4) according to the characteristics of continuous forest inventory data, using the method of allometric growth model, obtain the biomass like wood, plot level biomass and the interval of annual growth data; on this basis, the site quality quantitative and established the evaluation factor and biomass growth model between the site.
