Afforestation construction of Shanghai focuses on the target of improving urban ecological environment of Shanghai, and abides by the principle of adjusting measures to local conditions in a scientific and sound manner. In the project, construction units co-operate with the departments of planning, environmental protection and urban construction, etc., and change from the previous way of "making use of every bit of space for afforestation" to the current measure of "planning for afforestation construction", in which, the construction is carried out by combining the work of urban construction, remodeling of old blocks, moving away polluting factories and dismantling dilapidated houses as well as squatter houses so as to develop large pieces of land for greenbelt construction. At the meantime, based on ecological theories, the afforestation construction is carried out in forms of "circuit lines, planting, veranda and gardens" in an all-rounded way and large pieces of man-made ecological forests at suburbs are to be built. The construction is done by combining horizontal afforestaion and space afforestation, and the manner of integration of urban and rural afforestation is to be employed in the construction, thus bearing the characteristics of afforestation development for metropolis and reflecting the momentum of going beyond common practice development in afforestation construction. For the past five years, the total amount of newly built greenbelt has been over 5951.69 hectares, among which, public greenbelt is up to 3589.34 hectares. Per capita public greenbelt at downtown area increases from 1.96 square meters of 1996 to 5.5 square meters at the end of 2001; and afforestation rate has increased from 17% to 23.5%. There are 22 newly built century parks in Shanghai; such large public greenbelt projects as the greenbelt with a length of 46 kilometers surrounding Shanghai, and 1st phase of 100 meters forest belt project have been completed. 120 pieces of public greenbelts, each of which cover a space of more than 3000 square meters. Breakthrough has been made in the greenbelt construction at downtown area, with the successive completion of a number of greenbelts with ecological scenes such as Yanzhong Greenbelt, Huangxin Park, Taiping Bridge Greenbelt, Xu Jiahui Park (1st phase), Kaiqiao Greenbelt, Huashan Greenbelt and Daning Greenbelt, etc., which has effectively alleviated "hot island effect" of Shanghai. Thus, living environment and working environment of citizens in Shanghai are markedly improved and the new image of Shanghai as a metropolis is further reflected.
