【摘要】：林地是國(guó)家重要的自然資源和戰(zhàn)略資源,是森林賴(lài)以生存和發(fā)展的根基。開(kāi)展立地分類(lèi)與質(zhì)量評(píng)價(jià),對(duì)于實(shí)現(xiàn)適地適樹(shù)地科學(xué)造林、營(yíng)林、育林具有重要指導(dǎo)作用,對(duì)于科學(xué)管理林地資源,推進(jìn)生態(tài)文明和美麗中國(guó)建設(shè)具有重要現(xiàn)實(shí)意義。本文基于浙江省森林資源連續(xù)清查體系,利用固定樣地立地因子調(diào)查數(shù)據(jù)、林木生長(zhǎng)量連續(xù)測(cè)定數(shù)據(jù)等,對(duì)浙江省立地分類(lèi)與質(zhì)量評(píng)價(jià)體系進(jìn)行了探討,主要有以下幾方面內(nèi)容：(1)根據(jù)山地丘陵和平原林地立地主導(dǎo)因子不同,分別采用逐步回歸分析法、定性與定量分析相結(jié)合法等,篩選立地分類(lèi)主導(dǎo)因子,建立了浙江省立地分類(lèi)系統(tǒng),將全省劃分為2個(gè)立地區(qū),9個(gè)立地類(lèi)型區(qū),建立20個(gè)立地類(lèi)型組,52個(gè)立地類(lèi)型。(2)根據(jù)建立的立地分類(lèi)系統(tǒng),采用數(shù)量化方法和層次分析法,分別對(duì)每個(gè)立地單元進(jìn)行定量化評(píng)分,評(píng)定各立地單元的立地質(zhì)量等級(jí),建立了立地質(zhì)量評(píng)價(jià)體系。全省共分262個(gè)立地單元,分別評(píng)為一等地、二等地、三等地、四等地、五等地5個(gè)質(zhì)量等級(jí)。(3)根據(jù)2012年浙江省森林資源復(fù)位調(diào)查樣地?cái)?shù)據(jù),利用構(gòu)建的立地分類(lèi)系統(tǒng)和評(píng)價(jià)體系,采用系統(tǒng)抽樣統(tǒng)計(jì)方法和地統(tǒng)計(jì)Kriging插值法,評(píng)價(jià)了全省林地的立地質(zhì)量,制作了立地質(zhì)量分布圖。(4)根據(jù)森林資源連續(xù)清查數(shù)據(jù)特點(diǎn),采用異速生長(zhǎng)模型法,獲取了樣木、樣地水平生物量和間隔期內(nèi)生物量年均生長(zhǎng)量數(shù)據(jù)；在此基礎(chǔ)上,建立了立地因子與生物量生長(zhǎng)量間的立地質(zhì)量數(shù)量化評(píng)價(jià)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.
