Abstract

Global atmospheric CO2 concentration has risen sharply since the industrial revolution, the concentration increased greenhouse effect caused by CO2 and CH4 and other greenhouse gases most scientists confirmed that the main reason for global warming. The convening of the climate summit in Copenhagen in 2009, showing generally agree that global greenhouse gas emissions cause global climate change. The Chinese government announced before the summit, to the carbon dioxide emissions per unit of GDP in 2020 from 40% to 45% lower than in 2005. Chongming clear as Shanghai sustainable development an important strategic resource in Chongming planning, the the ecological island's development orientation. In November 2009, the Ministry of Science and Technology and the Shanghai Municipal People's Government in 2009 the Ministry of Municipal consultation meeting on the launching Chongming Ecological Island green economy pilot demonstration \construction at the same time, in the development of low-carbon agriculture, community and industry to innovate, contribute to Shanghai's industrial structure adjustment and Adding Carbon Sinks reduction, and may become a model for the development of low-carbon economy of the country and even the world . This article is in the context of Chongming, analyze and summarize the results of previous studies, as the main data source to existing Chongming wetland ecosystem carbon flux monitoring site data and MODIS imagery data, combined with GIS technology database technology, software engineering, and to establish a the Chongming Island wetland carbon source monitoring database, source / sink model library and the thematic image database based on the automatic interpretation of remote sensing information and on this basis to achieve \coding and development, to achieve a regional wetland carbon fixed carbon stocks in the grid network calculation, Chongming wet land ecosystem carbon fixed release and archived for long-term calculation and assessment provides data and technical support, for national and Shanghai carbon growth sinks emission reduction work to provide the necessary knowledge, technology and data stock. This paper the main results are as follows: First, the use of database technology, data for Chongming carbon source measured foundation design and online monitoring database Chongming carbon source carbon sinks; combination of remote sensing technology, and software engineering technology based on MODIS imagery data, the establishment of the Chongming Island database as well as the combination of remote sensing images thematic model library and GIS technology-driven carbon source carbon sink estimation model based on remote sensing, initially built Chongming the wetland carbon source carbon exchange model library. And management system developed on the basis of these databases, Chongming carbon sources and carbon sinks data and results visualization integrated management. Secondly, the use of the development of RS and GIS integration technology on the basis of the the the measured carbon source carbon sinks databases, remote sensing thematic Library and the model library, use NET platform C # language Chongming wetland carbon source carbon sequestration monitoring and management system. System to achieve the integration of RS and GIS: use of the RS module of the remote sensing data preprocessing and parameter automation inversion, the use of technology model library source / sink estimates visual display of results, the use of GIS technology. Early in the remote sensing data processing, the use of the IDL fast graphics display and image processing capabilities, and a visual display of the process, and enables users to see that change. Results of performance through the form of thematic maps makes intuitive performance and diverse. Finally, on the basis of previous work, the main function modules in the system, for example, doing application analysis and evaluation. The results show that the system is able to provide support as a carbon source carbon sink estimates.
