Study On Dynamic Characteristics Of Wetland Based On LANDSAT Data-Comparison Analysis Of Protected Xianghai And Momoge Nature Reserve

Xianghai National Nature Reserve and the Momoge National Nature Reserve is located in Baicheng City,Jilin Province,is an important wetland ecosystem in Jilin province.The wetland basic definition is a comprehensive natural factors produced by the interaction between water and land,wetland is the most important for the survival of the environment the ecological landscape and human nature to have the most biological diversity,which has links to water,flood and drought,climate regulation,protection of the coast and maintain diversity results.Marine species,forest and wetland were referred to the earth "three kidney",namely the earth on the three most important ecological system.In this paper,through the TM Landsat satellite image data support the features of the type of analysis to reserve and Momoge nature reserve vector machine classification method using SVM,so as to obtain the dynamic change of wetland change features of land use data,and by using the method of landscape ecology analysis,quantitative analysis of the dynamic spatial pattern of land utilization and protection of the wetland area change,on the basis of the initial reasons for the change of wetland landscape pattern analysis,to provide scientific support for the Xianghai National Nature Reserve and Momoge wetland protection and management.In order to Mo 'National Nature Reserve and multi period TM remote sensing image in Xianghai National Nature reserve from 1978 to 2016 the basic information and related data,topographic map,analysis of administrative zoning map and other relevant data combined.Firstly under the ENVI software at the remote sensing Image processing,such as image stitching,cutting,rotating projection,such as resampling,according to the observation data at interpretation,held on the platform of ARCGIS spatial analysis,statistical analysis,from 1978 to 2016 in Momoge nature reserve and Xianghai Nature Reserve in various types of wet land area change wetland type statistics and 1978 to 2016 period data.The results show that: to the sea marsh reserve and Momoge nature reserve wetland ecosystem in the area more than ever greatly reduced,and the emergence of wetland fragmentation and growing trend,finally obtains the Momoge protected areas and protected areas to the sea are due to man-made and natural factors makes the wetland system relatively the degradation,affected by human factors and more serious.Momoge protected areas and protected areas to the sea by reducing the area of wetland and wetland fragmentation trends and reasons are different,the two protected areas were analyzed,so as to find out the similarities and differences among them,and further research and discussion.The final conclusion,summed up the Momoge nature reserve and Xianghai wetland change protection dynamic similarity and diversity,thus for wetland protection and management in China is proposed.Constructive advice,that is,to increase the number of protected areas and the construction of Wetland Reserves.
