Comparative Analysis The Landscape Patterns And The Ecosystems Service Values Changed Of Chongqing City And Rural Areas

Selecting two times Landsat TM remote sensing images in June 1998 and June 2008 of Liangtanhe River Basin(in Shapinba District) in Chongqing city and Gaotanhe River Basin in Chongqing rural area,using GIS and RS technology, using Mathematics statistics and FRAGSTATS .et methods for interpreting and statisticaling data relevant to the valleys, On the theories basis of LUCC and Landscape ecology and Ecosystems service values, adopting Landscape pattern analysis,comparative analysising the landscape pattern of the situation on the vertical pattern characteristics in contrast of the two valleys in the study of 1998 year and 2008 year, comparative analysising the landscape pattern of dynamic change in contrast of the two valleys from 1998 year to 2008 year and comparison of two basin scenery changes and drive out the driving mechanism of Chongqing zone directly under the start of 10 years,then,on this basis of that, comparative analysising the dynamically and the pattern of the ecosystems service values of the two valleys. The main results and conclusions of this thesis are listed as follows: 1.The differences of the landscape pattern of dynamic change of the Liangtanhe River Basin(in Shapinba District) and Gaotanhe River Basin from 1998 year to 2008 year is in the scenic area and spatial distribution differences.2.In the landscape pattern of dynamic change of the driving forces of the two valleys,Liangtanhe River Basin(in Shapinba District) have one more driving force of government decision than Gaotanhe River Basin,and in the driving forces,the economic and social development and location condition in the driving role of it's strength and results is different of the two valleys.3.In the activities of human interference of the Liangtanhe River Basin(in Shapinba District) and Gaotanhe River Basin from 1998 year to 2008 year,the total ecosystems service values of the two valleys are decrease.The ecosystems service values of each landscape type changed in the time and space of the two valleys followed the view of the each landscape type mutual transferred.The research on the comparative analysis of the landscape pattern and the ecosystems service values dynamically of the Liangtanhe River Basin(in Shapinba District) and Gaotanhe River Basin of Chongqing from 1998 year to 2008 year,providing some certain scientifics for economic development and environmental control of the Chongqing city and rural areas.
