三江平原湿地保护措施的初步研究

三江平原是我国最大的湿地集中分布区。但由于水土资源的不合理开发利用,造成湿地萎缩,并导致土地沙化、水土流失、水旱灾害频繁发生、生物多样性明显下降等诸多环境问题。简述了三江平原沼泽湿地的主要功能,分析了造成湿地萎缩的主要原因,提出了三江平原湿地保护的基本措施。

Study on the Wetland Protection Measurements of the Three-rivers Plain

s: The Three-rivers Plain is the largest area where wetlands are distributed concentratedly. But the unreasonable development and utilization of water and land has resulted in many environmental problems such as land sandization, erosion, more water disasters and the notable decline of biology multiformity. The paper summarizes the main function of wetlands in the the Three-rivers Plain briefly, and then analyses the central causes which bring on the decrease of wetland area, puts forward some measurements to protect wetlands efficiently at the end.
