| In recent years, the wetland resources have been severely degraded in china. The NorthChina plain is the most important settlement. The wetland condition closely related to human life.The geological environment in soil also has close relation to the wetland evolution. This article isbased on "The geological environment monitoring of soil and water in the typical region".through the comparison and analysis of water and soil data for nearly ten years, Combined themeans of remote sensing and field surveys, I have reach the conclusion that the generalizationrelationship exist between geological environment of soil and water. and wetland degradation. Itwill give the right direction to the investigation and monitoring of wetland resources and impelgeological environment monitoring and management scientifically.Using2009TM data and2001ETM data with ENVI software analysis，I get theinterpretation of the main types of wetlands in the region. The wetland has some types, such asrivers, artificial canals, reservoirs and so on.Aquaculture ponds and salt fields. And thenestimating changes in various types of wetland area in the last decade and a variety of wetlandtypes that convert. I also carry out comparative analysis of evolution for three typical wetlands inthe study area. The results are really well explained the evolution of the research area in the lastten years.In thesis writing stages, I collected the2000to2010soil and water monitoring data of thestudy area, including groundwater level data, groundwater quality data and Three-phase soil datafor2005-2006，2008-2009.Firstly, I summarize the overall evolution characteristics of soil andwater in the last ten years. and then filter for data to get the evolution characteristics ofgroundwater quality, groundwater level and Shallow soil elements in typical wetland.The fieldsurvey job in the different types of wetlands in the region carried out in2011.It verified theresults of remote sensing analysis very well. |
