大庆湿地时空变化分析

Analysis of temporal and spatial variation of wetland in Daqing

大庆湿地是黑龙江省湿地相对集中的地区,它对大庆的气候、环境和经济的发展有着非常重要的影响。然而,近几十年来由于大庆人口的增长和经济的发展,大庆湿地正在遭受着日益严重的污染和破坏。为了保持大庆湿地的生态平衡,必须找到一条改善大庆湿地生态环境的出路。同时,随着地理信息系统在科学研究中的广泛应用,将GIS空间分析方法应用到湿地的研究中已成为必然趋势。本文以大庆湿地为研究对象,综合利用2001年和2007年数据,分析大庆湿地的时间变化特征;利用1988年、1996年和2010年数据,充分运用GIS空间分析方法,重点分析了大庆市区湿地的空间变化特征,并分析其原因,最后提出保护大庆湿地生态系统的合理化建议。

Daqing wetland is the wetland in Heilongjiang province is relatively concentrated areas ,has a very important influence on the climate of Daqing ,its environmental and economic development.However ,in recent decades due to the Daqing population growth and economic development ,Daqing wetlands are suffering in-creasingly serious pollution and destruction.In order to maintain the ecological balance of the wetland in Daqing,Daqing improvement must find a way out of the wetland ecological environment.Meanwhile,with the geographic information system is widely used in scientific research ,the GIS spatial analysis method is applied to the study of wetlands has become an inevitable trend.In this paper,Daqing wetland study,utilization in 2001 and 2007 data,analyze time-varying characteristics of Daqing wetlands;use in 1988,1996 and 2010 data, make full use of GIS spatial analysis methods ,focusing on analysis of Daqing urban wetlands spatial variation , and analyze its causes,and finally to make reasonable suggestions to protect Daqing wetland ecosystems.
