[Abstract]:By interpreting and analyzing the remote sensing images of Tianjin Binhai New area in 1976, 1984, 1993, 2000, 2006 and 2013 for nearly 37 years, and combining the historical data of the six periods and the field survey data, this paper analyzes and analyzes the remote sensing images of Tianjin Binhai New area in 1976, 1984, 1993, 2000, 2006 and 2013. The evolution process of reclamation in Tianjin Binhai New area in different periods, the temporal and spatial changes of shoreline changes and the temporal and spatial changes of wetland landscape pattern were analyzed respectively. Based on the DPSR conceptual model, the evaluation index system of the influence mechanism of reclamation on coastal and wetland pattern and process is established, and the comprehensive optimization of the model is carried out. The main results are as follows: (1) based on the understanding of the classification of national reclamation and the use of the sea area of the 1993 World Coastal Congress, the types of reclamation utilization in Tianjin Binhai New area are classified by combining with the historical literature and field survey of Tianjin Binhai New area. Based on the remote sensing images of Tianjin Binhai New area in the past 37 years and other data of social resources such as maps and maps, the 3s technology is used. The evolution of reclamation in Tianjin Binhai New area during the past 37 years from 1976 to 2013 was reproduced by ArcGIS10.0 and MapINFO11.0. By studying the evolution process of reclamation in Tianjin Binhai New area, the method of shoreline extraction from silt coast in Tianjin area is understood and mastered. From 1976 to 2013, it is concluded that the changes and characteristics of shoreline changes in Tianjin Binhai New area (Tianjin Binhai New area) from 1976 to 2013. In this paper, the wetland type distribution map of Tianjin Binhai New area is established by combining supervision classification and visual interpretation. The changes of wetland pattern in Tianjin Binhai New area in recent 37 years are reappeared. By selecting landscape index and changing law of landscape index, we can find out the relationship between different wetland landscape types.) take Tianjin Binhai New area as an example. Based on the principle of DPSR conceptual model, a model of the influence of reclamation on coastal and wetland patterns and its change mechanism is established. The model is based on the four aspects of driving force, pressure, state and response, and combines with the historical data of sustainable development. Through the method of calculating weight and comprehensive index, this paper analyzes and expounds the internal relations among reclamation, shoreline and wetland, as well as the relationship between them and other factors in the model. Therefore, the comprehensive optimization measures are carried out on the model of influence mechanism, and the three main research objects, including reclamation, shoreline and wetland, are optimized.
