【摘要】 目的　为了解西安湿地资源现状和湿地环境的变迁,保护和开发利用湿地资源及湿地在西安生态环境与经济社会发展中的地位和作用。方法　经过对遥感资料的分析,并结合现场测量和人工调绘,系统分析研究西安湿地资源的类型、分布、面积、功能等基本状况。结果　首次对西安湿地进行了分类,查明西安地区湿地面积为900.96km2,占全市总面积的8.9%,其中天然湿地面积为822.05km2,占湿地总面积的91.24%,人工湿地面积为78.91km2,占湿地总面积的8.76%。结论　天然湿地面积每年以0.83%速度减少,天然湿地面积呈下降趋势,人工湿地面积变化呈上升趋势,湿地资源在逐年减少。湿地的生态功能正在衰退,湿地生态环境的恶化,影响到地区环境变化。更多还原

【Abstract】 AimTo find out the present situation of Xi′an wetlands resource and change of wetlands environment, protect and develop wetlands resource and make clear of the status and function in Xi′an ecological environment and development of economic society.MethodsThe type of distribution area and function of Xi′an wetlands resource are studied by analyzing remote sensing data, surveying on the spot and manual drafting.ResultsAt the first time, Xi′an wetlands have been classified and the area of it is 900.96 km~2 covering 8.9% only in total area of Xi′an, in which the area of natural wetlands is 822.05 km~2 covering (91.24)% in the total area of wetlands, the area of man-made wetlands is 79.91 km~2 covering 876%.ConclusionThe area of natural wetland trend to the decline decreased by 083% each year, however the area of man-made wetlands is upward trend. The wetlands resource is decreasing year by year. The ecological function and environment of wetlands is failing and worsening, so the above-mentioned will have influence on the region environment.更多还原
