Analysis of spatial distribution characteristics and growth state of Pinus tabulaeformis in Mountain Tai
摘要
Abstract
This work was to discuss the spatial distribution characteristics and growth state of Pinus tabu-laeformis in Mountain Tai,and to analyze the influence of environmental variables on its growth state.Based on the digital elevation model(DEM)and"one map"of forest resources survey data,the geo-in-formatic graphics of the spatial distribution of Pinus tabulaeformis was established.Then the maximum NDVI of the growing season of Pinus tabulaeformis in the study area from 2000 to 2018 was extracted to characterize the growth state of Pinus tabulaeformis,and analyze its changes under different site condi-tions.The findings indicate that(1)Pinus tabulaeformis pure forest is mainly distributed in the areas of north,northeast and northwest slopes at an altitude of 850～1500 m(40%～90%of the area),while the mixed forest of Pinus tabulaeformisis mainly distributed in the areas of hillside valleys,ridges,north-east,east and southwest slopes at altitudes of 400～1 050 m and 1 300～1 450 m(20%～30%of the area).(2)From 2000 to 2018,the growth state of Pinus tabulaeformis forest showed a positive trend,and the area share with significant NDVI increase(9.82%)and extremely significant increase(13.56%)was larger than those with significant NDVI decrease(4.48%)and extremely significant de-crease(2.69%).(3)The growth state of Pinus tabulaeformis forest is better in the area of elevation 600～1 400 m,slope<5° and 25°～55°,soil thickness>35 cm,and in the north,west and northwest slopes.Based on the analysis of the spatial distribution characteristics of Pinus tabulaeformis forest and the change of its growth state under different site conditions,this study summarized the site conditions conducive to the growth of Pinus tabulaeformis,and provided scientific basis for the health conservation of Pinus tabulaeformis forest and the protection of old and famous trees.关键词
