Analysis And Design On Landscape Pattern Along The Songhua River In Jilin City

With the speedup of the urbanization, the urban population increased year by year, thecity in the rapid development has also brought serious urban pollution, such as thedeterioration of ecological environment, which the city’s ecological environment of the urbanlandscape pattern change will bring direct impact. The waterfront area has its own uniquenatural advantages, which is the organic combination of the waters and the land of urbanpublic space, and it is the most complex ecological resources and natural landscapes, the mostvulnerable areas, but also is the most obvious areas by human impact on. So this paperchoose the area on both cides along the Songhua River in Jilin city as the study area, andResearch on the landscape pattern changes and ecological effect, and provide the scientificbasis for planning and management of waterfront area.In this paper use the both sides along within10km of Songhua River in Jilin city as thestudy area. Useing3S techniques and mathematics model, analysis on the changes oflandscape structure and driving force in Jilin City in1980,1995,2000,2005and2010years.The results show that: the Affected by the economic development and related policies, urbangreen area decreased and then increased trend of urban construction land area first increaseand then decrease variation of farmland gradually decrease trend, while the water area willremain no obvious changes. Landscape pattern of the city by the influence of the artificialfactor more and more big, diversity index volatility goes near the1.2,0.87,0.13fluctuates upand down, the overall landscape pattern of fragmentation are higher, a variety of plaquecategories in the landscape was the development trend of equalization. Through theoptimization of the landscape structure in recent years, especially water green "project is thedesign and implementation, climate effects, cultural effects have significant implications forthe environmental effects of Jilin City, Jilin City full-year air quality for more than twothenumber of days was significantly increased. The backdrop of the rapid warming of the entirenortheast region, Jilin temperature warming rate is lower than the entire northeast region of0.03℃/10a; precipitation and sunshine hours change is easing. But the "urban heat island"effect is still obvious. In recent10years, despite the landscape pattern in Jilin city has obvious improvemented,but there are still many malpractice in the urban landscape pattern. Such as green spacedistribution and not reasonable design of Embankment. The Songhua River green corridorrole is not sufficiently realized and so on. Paper makes the corresponding landscapeoptimization design, increase of green land, put forward the green landscape pattern change,and the use of natural type of Embankment fully mining characteristics cultural enhancehumanistic landscape measures. It will have a guiding significance for the north landscapepattern changes and landscape design.
