RELATIONSHIPS BETWEEN BIOMASS AND VEGETATION INDEX OF PICEA SCHRENKIANA VAR.TIANSHANICA IN WESTERN TIANSHAN MOUNTAIN
摘要
Abstract
Remote sensing and forest resource survey data were used to extract age class information for Picea schrenkiana var. Tianshanica. Eighteen vegetation indices were selected to describe relationship between age class biomass and ratio vegetation index, the ratio of normalized vegetation index, and other vegetation indices in western Tianshan mountain region of Gongliu in Xinjiang. Data indicated that the correlation coefficient between overall biomass and vegetation indices is lower than correlation coefficient between age-class biomass and vegetation indices. It can therefore achieve better results to study the relationship between age-class biomass and vegetation indexes. Biomass of each age class Picea schrenkiana forest was more correlated to 7ndv and ITM4/3 in all vegetation indexes. Young forest biomass and Itm4/3 is most correlated, with correlation coefficient of - 0. 794. Middle-age forest biomass and Indv , Itv was most correlated, with a correlation coefficient of 0. 506. Middle-age forest biomass and TVIS123 also showed correlation, the correlation coefficient was -0. 506. Near mature forest biomass and ITM4/ showed correlation, the correlation coefficient being at 0. 647. Mature forest biomass and Itm4/3 , Indv and Itv showed correlation, the correlation coefficient was 0. 532. Excessive mature forest biomass and Itm4/3 showed correlation, correlation coefficient was 0. 715. Correlation between biomass and vegetation index has important theoretical meaning and great practical value for effectively monitoring biomass using remote sensing data.关键词
