Because he spent the most time of his life in the Lake District,a lot of poems he wrote are about landscapes and nature,and at the same time show his sentiment to nature. After studying I conclude that there was really significant influence on his attitude toward the nature,the theme of his poetry.展开更多

According to the census in spring of 1984, the total number of Red-crowned crane is 72 individuals and 20 nests. So that this ground census has recorded 59 individuals more than the aerial survey of 13 individuals, and the percentage of nesting individuals in this flock is 55.6%, which is obviously higher than 36.9% of the average ratio in China. After this, in fall of 1984 and in spring of 1985 and 1986, we repeated the same censuses three times in the same districts, the results indicated that the flock of the crane in Khanka Lakes District is stable basically, but some individuals interchange with opposite flock of USSR because of gcgraphical adjoin.So, we believe this flock in China and that flock in USSR belong to the same population and suggest two countries should act in concert to studing on this population in future. Meanwhile, the aerial servey cooperate with ground census, it is the best way for reducing missing crane and achieving to high precision of census. From this, total number of Red-crowned crane in China is 542 individuals (483+59 ind ividuals).展开更多

To achieve this core target, the paper first identifies main indicators describing healthy lake ecosystem and defines the external factors that can influence the health of lake eco-system. Then based on this, two kinds of urban planning methods are proposed to maintain the stability of lake eco-system health through controlling the external factors that can affect the health of lake eco-system. The first is to propose controlling factors in urban planning, such as division of ecological sensitive zones, controlling the development intensity, population capacity and types of industry in the lakeside regions and the second is to construct a monitoring and early warning system for lake eco-system health. The theories and methods mentioned in this paper have been applied to the planning of Wuhan Wutong Lake eco-city.展开更多
