泰山世界遗产地刺槐林地学信息图谱分析

基于2014年10月WorldViewⅡ遥感影像和DEM数据,结合泰山林场同期二类资源调查数据,对泰山世界遗产地的刺槐林(Robinia pseudoacacia L.)进行目视解译。然后通过建立地学信息图谱分析泰山刺槐林在主要地形因子(海拔、坡度和坡向)影响下的分布规律,结论如下:(1)刺槐纯林及其混交林,类型共计30种,投影面积约807.58 hm^2,其中刺槐纯林投影面积约454.76 hm^2,占刺槐林总面积的56.31%;(2)刺槐林分布在250—1200 m的海拔范围,集中分布在500—900 m的斜坡、陡坡和急坡,其中刺槐纯林在海拔250—300 m全部分布在平坡和缓坡;(3)刺槐林主要分布在半阴坡、半阳坡和阳坡,半阳坡分布最多,其中刺槐纯林在海拔1100—1200 m几乎全部分布在半阳坡和阳坡。

Geo-informatic spectrum analysis of Robinia pseudoacacia forests in Taishan World Heritage site

Based on the remote sensing image of WorldViewⅡin October 2014,DEM data and the forest resource inventory data of Taishan Forest,the Robinia pseudoacacia forests of Taishan World Heritage site were visually interpreted.Then the Geo-informatic spectrum was established to analyze the distribution of Robinia pseudoacacia forests under the influence of major topographic factors(altitude,slope and aspect)in the Mountain Tai.The main conclusions are as follows:(1)There are 30 types of the pure and mixed forests of Robinia pseudoacacia.And the total area of Robinia pseudoacacia forests is about 807.58 hm^2,of which the pure forests are about 454.76 hm^2,accounting for 56.31% of the whole Robinia pseudoacacia forests.(2)The Robinia pseudoacacia forests distribute in the altitude from 250 m to 1200 m and concentrate in the slope,steep slope and sharp slope in the altitude from 500 m to 900 m.And all the pure forests distribute in the flat slope and gentle slope in the altitude from 250 m to 300 m.(3)The Robinia pseudoacacia forests mainly distribute in semi-shady slope,semi-sunny slope and sunny slope,of which the semi-sunny slope is the most.And almost all the pure forests distribute in semi-sunny slope and sunny slope in the altitude from 1100 m to 1200 m.
