Analysis on Changes of Land Use Based on Transfer Matrix and Information Entropy---A Case Study of Zhongshan Mountain Scenic Area
摘要
Abstract
The change in land use types in Zhongshan Mountain Scenic Area of Nanjing Municipality during 1987 and 2002 was analyzed by using transfer matrix and statistical methods based on the data of the secondary for-est resource survey.The results showed that the area of coniferous forest and non-forest land in Zhongshan Mountain Scenic Area declined,while the broad-leaved forest and mixed forest composed of coniferous and broad-leaved tree species was increased from 1987 to 2002.There was a strong sense of hierarchy pattern with entropy values of land use type information of Zhongshan Mountain Scenic Area under 600 m scale.The whole scenic area could be divid-ed into two parts according to the information entropy values,where the higher value area was distributed in the Ming Xiaoling Mausoleum Scenic Area and the central part of Dr.Sun Yat-sen′s Mausoleum Scenic Area,whereas the lower value area was mainly concentrated in the Natural Scenic Area and Mountain Scenic Area.In 2002,the whole scenic area could be divided into three higher and one lower information entropy value areas,the higher val-ue areas were mainly located in the Ming Xiaoling Mausoleum Scenic Area,the central part of Dr.Sun Yat-sen′s Mausoleum Scenic Area and the northern part of the Natural Scenic Area,while the lower value area was located in the southern part of the Natural Scenic Area.The study showed that,the low information entropy value areas of the land types were reduced,and the high value areas were increased from 1987 to 2002.Overall,the information en-tropy value of Zhongshan Scenic Area was in a rising trend,which indicated that the structure of land use had be-come more diverse with stronger balance during that time period.关键词
