基于景观分维度的海岸带景观时空演变量化评价研究——以泉州湾为例

Quantitative Evaluation of Spatial and Temporal Evolution of Coastal Zone Landscape Based on Landscape SubDimensions: Quanzhou Bay as an Example

摘要:

海岸带是海陆统筹战略实施及国土空间规划的重点区域，利用遥感影像处理和 GIS 相结合的技术方式，基于生态学理论中的景观分维度因子，以泉州湾为实证研究典型，对多时相遥感影像的土地利用现状的数据进行统计对比，利用 1973 年以来 7 个时相的 MSS/TM/ETM 遥感资料，监测调查泉州湾入海口围垦后的景观变化，引入景观分维度指标，量化评估围垦后入海口 50 年的景观时空变化特征，探讨影响海岸线变化的主要原因，为理解海岸带潜在问题提供决策支持，并总结量化评价方式与路径，提出一种国土空间自然资源的监测与量化评价的参考方法。

Abstract:

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 decisionmaking 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.
