Quantitative Evaluation of Spatial and Temporal Evolution of Coastal Zone Landscape Based on Landscape Sub-Dimensions:Quanzhou Bay as an Example
The coastal zone is a key area for implementing the strategy of land-sea integration and land space planning.This study utilizes the technical approach of combining remote sensing image processing and GIS,based on the landscape sub-dimension factor in the theory of ecology,and takes Quanzhou Bay as a typical empirical study to statistically compare the data of land use status of multi-temporal remote sensing images,and utilizes the MSS/TM/ETM remote sensing data of seven temporal phases since 1973 to monitor and investigate the landscape changes after the reclamation of Quanzhou Bay.Using the MSS/TM/ETM remote sensing data of seven-time phases since 1973,the study monitors and investigates the landscape changes after the reclamation of Quanzhou Bay estuary,introduces landscape sub-dimension indicators,quantitatively evaluates the landscape spatial and temporal change characteristics of the estuary after reclamation for 50 years,explore the main reasons affecting the changes of the coastline,and provide decision-making support for the understanding of the potential problems of the coastal zone,as well as summarize the quantitative evaluation methods and paths,and put forward a reference method of monitoring and quantitative evaluation of the natural resources of the national land space.
