Basically, most of them are freshwater wetlands and have great influence on the primary economic activities such as agriculture and fisheries of the country. Due to its important role in the harmonizing ecosystem, wetlands demand much attention as a significant part of our environment. Matasagar and Sukhsagar are very important historical wetlands of Bangladesh. But those are endangered today due to lack of public awareness of the dangers of their activities to the environment and unbridled profit making activities of the commercial users of the wetlands. Comparisons of maps and Google images from 1933 to present have shown that the forest areas of the wetlands have been progressively destroyed, and these have greatly affected the biodiversity of these areas mentioned. GIS (Geographic Information System) and remote sensing techniques are used to identify the changes in the aerial extent of those wetlands. This study also tried to explore present environmental conditions by in-situ observation. This is high time;some serious steps should be taken to ensure the conservation and preservation of these areas mentioned. 展开更多

Through careful study, it found that the key and difficult points of affecting and restricting Xi'an to reach the model city construction standards in provincial and national levels were "urban air environment quality standards" and "water qualification rate of urban water environment function area". In order to tackle with the weak links, highlight the important points and focus on the difficult points to strengthen scientific and technological innovation, we actively explored new ideas and ways to resolve the dilemma in meeting the two standards of model city construction, and we managed to put forward the countermeasures to resolve the dilemma through innovating system and mechanism. "Place master system" should be carded out quickly to meet the "urban air environment quality standards", while "river master system" should be implemented as soon as possible to reach the "water qualification rate of urban water environment function area". The aim of this study was to enhance the qualification rates of the indicators for model city construction to make Xi'an successfully pass the provincial and national assessment of model city construction through dealing with the weak links to accelerate the realization of becoming model environmental protection city. 展开更多

Situated in the hinterland of the Qinghai Xizang Plateau, the eco environment of the source regions of the Changjiang (Yangtze) River and the Huanghe(Yellow) River are getting worse in recent years and has attracted increasing attention of researchers around the world. This paper discusses several major problems concerning the eco environment of the source regions. The authors hold that the two eco environment extents of the source region of the Changjiang River should be demarcated with the confluence of the Deng’ailongqu River to Zhidoi as its boundary, or 1.15×10 4 km 2 larger than the hydrological source area; while that of the Huanghe River should be delimited with Medotangumaxia in Darlag County as its limit, or 1.84×10 4 km 2 larger than the hydrological source area. The eco environment of the source regions with vegetation, soil, wetland, lake and river as the main elements, has always been affected by climatic changes, freeze thaw processes (including frozen soil freeze thaw processes and glacial snow cover freeze thaw processes), rodent damage and human activities. From an evaluation angle of fragile ecosystem, a study index system is established and several important issues for future research are suggested. 展开更多
