Monitoring Of Eight_borough Parks Green Land And Relation Research With City Environment, Beijing

City green land is a certain bound virescence ground or area ,it is formed by planting arbor,arborbush and herb suitable,and it cooperate with environment to create natural conditions.The park green land system is viewed as a important subsystem in the city green land.it not only is an important component in making up of urban green land sight,but also is playing an important ecological function in improving urban environment. Reaearching the relation between park green land and urban environment has a important meaning in instructing the benign development of urban environment.This Paper utilizes RS(Remote Senseing)technology and GIS(Geographical Imformation System)technology and combines other reference materials to monitor the registered park green land in Beijing suburbs eight districts.On the basis of monitoring,the Paper analyses the some relations between urban park green land and urban environment include city park green land and urban hot environment ,park green land and urban water quality and the relation between the park green land and urban biological sight from the viewport of ecological function of the urban green land. And concrete speaking this Paper includes some research work and achievement as following:(1) Use the RS(remote sensing technology) to monitor the current situation of the park green land of the eight districts of Beijing City, And acquire the current situation information include the characteristic of distribution of park green land ,space distribution and view structure about the park green land of the eight districts of Beijing city.(2)This Paper analyses the hot charastic of the eight districts of the city by making use of meteorological materials and remote sensing data, and combing the distribution characteristic and the space distribution of the park green land of Beijing City ,the Paper analyse the function of drop in the temperature of environment to city hot of Beijing the eight districts of the city park green land. (3) Utilize water quality to appraise the law of pollution index, the Paper appraises water quality according to the water quality monitoring data of ten parks of the eight districts of the Beijing city, and analyses the impace on park green land of water quality on the basis.(4)Through the analysis of the view structure and afforesting of the park of the eight districts of the Beijing city. The Paper has analyseed the biological view characteristic of the park green land from the view of the sight makeup and afforested of park.,and has proposed the countermeasure and suggestions to the afforestation of the park.Throught the analysis above, It can be known that city park green land is regarded as a green window of city, and play an important role in urban environment. First urban park green land reduce city hot temperature, and there is a minus relativity between space distribution , area and urban hot temperature. Secondthe water quality environment relatively bad of the lakes of the eight districts of Beijing.,the situation influences ecological environment of the park green land. Third the view structure and afforests of the park green land maintain the bio-diversity of the city of Beijing ,become an important carrier of bio-diversity embodiment.
