文章摘要
目前,针对滨海湿地生态系统碳过程模型构建的研究有一定的进展,但在如何耦合生态过程模型与遥感技术去估算湿地碳源/汇的时空格局动态方面仍处在尝试阶段。通过对湿地生态系统碳过程模型和遥感反演模型的构建,数据库技术和地理信息系统(GIS)软件的二次开发完成了“滨海湿地碳源/汇模拟系统”软件的开发。在此基础上,以区域遥感卫片、 野外湿地监测和气象观测数据为主要驱动变量,模拟了崇明东滩湿地潮间带芦苇群落和旱生芦苇群落的碳收支时空格局动态。系统可为管理者估算区域尺度滨海湿地碳源/汇时空动态,预测这一类型湿地碳汇潜能在人类活动和气候变化影响下的发展趋势,为管理者提供一定的理论与技术支持。
Abstract
At present, the study on constructing the ecosystem carbon process models of coastal wetland has made some progress, but it is still in trial stage that how to couple the ecological process model and remote sensing inversion to estimate spatiotemporal pattern dynamic of wetland’s carbon source/sink. We complete the development of “coastal wetland carbon source/sink simulation system” software by constructing wetland ecosystem carbon process model and remote-sensing inversion model as well as the secondary development of database technology and geographical information system (GIS) software. On this basis, we take the regional remote sensing satellite photographs, the wild wetlands monitoring data and the meteorological observing data as key driving variables, and simulate the carbon budget spatiotemporal pattern dynamic of intertidal bulrush community and dry reed community in Chongming eastern tidal flat. The software system can help managers to estimate spatiotemporal dynamic of carbon source/sink on coastal wetland in regional scale and predict the developing trends of the carbon sink potentials of such kind of wetland under the influences of human activities and climate changes, which provides certain theoretical and technical supports for managers.
