摘要
松嫩平原存在着大量弱碱性湖泊和泡塘 ,构成了独特的盐碱湿地类型 ,在区域资源环境系统中占有重要地位。腰泡作为松嫩平原弱碱性湖泡湿地的典型之一 ,其生态系统具有生物多样性相对较好和食物链较短的优点 ,但动植物的数量关系反映出系统结构失调和功能受阻的缺陷。根据腰泡生态系统物流特征 ,以建设渔 稻 草 禽 畜的复合模式为目标 ,提出了进行生态农业开发的具体措施。
In Songnen Plain, there is about 16 340 square kilometres of saline alkaline wetland, which mainly consist of a lot of alkaline lakes, now occupying an important place in the system of regional resources environment. The saline alkaline wetland is the result of saline alkalization of wetland, showing degeneration of entironment. It has great significance to harness and develop saline alkaline wetland either for the recovery of enviroment or the development of agriculture. Among the alkaline lakes, there are a lot of alkalescence lakes and ponds, which form special kind of wetland and occupy an important position in the system of regional resources environment. Yaopao Lake is one of the typical alkalescence lake wetlands in the Songnen Plain. Its ecosystem boasts such excellence as better bio diversity and short food chains. But the quantitative relation of animals and plants reflected the shortages of imbalance of ecosystem structure and functional disorder. Finally, the paper points out such concrete measures for eco agricultural development as fishery, breeding of poultry, planting rice and reed according to the ecosystem characteristics in order to build the model of paddy reed fishery poultry domestic animal livestock.
