摘要
选自中国科学院国家科学数字图书馆(CSDL)中的VIP维普中文期刊网1989年~2003年和中国知识基础设施工程(CNKI)自1994年~2003年间,以三江平原为关键词,同时包括挠力河和别拉洪河等三江平原典型流域湿地公开发表的湿地研究论文为对象,分别对其加以分析归类.认为20世纪90年代初期在该区以湿地农业和资源开发利用研究为主;中后期以资源开发和自然环境变化为研究方向,生物多样性和流域治理领域研究明显加强;2000年之后,从资源开发到湿地环境变化、湿地物质循环、生物多样性、湿地结构、功能、湿地评价、湿地研究技术与手段、湿地保护和管理等各项研究的内容和范围明显拓宽.论文对三江平原湿地科学的研究现状和未来研究内容及其在国内湿地研究中的地位作了评述及展望.
Sanjiang plain is one of the largest wetland in China. It has become an important commodity grain base in China after more than 40 years exploitation. At the same time, the wetland area has decreased sharply. Destruction of wetlands and some environmental problems are attracting more and more attention. The author searched and classified the literature referring to the wetland services from Chinese national science digital library (CSDL) from 1989 to 2003 and China National Knowledge Infrastructure (CNKI) from 1994 to 2003. The trend of wetland research is shown as:the main researches in Sanjiang Plain are the exploitation of agriculture and resources from 1989 to 1994 which includes large-scale reclaiming wetland and its effects on environment, the method of promoting rice (soybean, corn, wheat, paddy) yield, the utilization of agricultural fertilizer, the large scale mechanization in cultivated technology, and the potential of agricultural exploitation. The articles from 1995 to 1999 researched on animal and vegetable and increased gradually, of which the leading contents were resources exploitation, environment characters description, and the management and restoration of watershed. After 2000, wetland researches focused on the exploitation of agriculture and resources, wetland change, substance circle, biology diversity, the structure arid function of wetland, wetland assessment and protection, and so on. From 2000 to 2003, there were about 152 articles in VIP, which focused on Sanjiang plain. At the same time, there were 1 363 articles in VIP and 1 638 articles in CNKI, which studied on wetland, most of which were wetland agriculture. The difference between the research after 2000 and the previous is that people begin to pay more attention to the adjustment of agriculture constructer and the intensive agriculture. Wetland change is also an important trend in Sanjiang Plain, which includes wetland climate, hydrology, soil and landscape change. Substance circle includes the emission/uptake of gr
