| With the rapid development of urbanization, the construction quality of urban green district network system has increasingly growing influence to urban residential environment, and the environment green quality of petroleum chemistry industry area even directly affects the quality of life. With the strategy of sustainable development and People's increasing environment consciousness, the green of petroleum chemistry industry area is getting more and more important. Therefore, it is necessary to intensify the construction and to research the theory of petroleum chemistry industry area at the same time. The paper used Nanjing as an example. With present condition investigation of petroleum chemistry industry area environment, the topic was discussed on its green quality and designation as follows:1. The research progress was reviewed, the existing construction problems of Nanjing petroleum chemistry industry area were discussed, and the main contents of this research were introduced briefly.2. The paper selected 10 typical petroleum chemistry industry areas in Nanjing such as First Chemistry Industry Factory, Nanjing Chemistry Fertilizer Factory, Nanjing Oil Refining Factory, Alkyl Benzene Factory, Nanjing Chemistry Industry Factory, Yangzi Oil Refining Factory, Alkene's Factory, Chemistry Industry Factory, Sweet Smell Hydrocarbon Factory and Plastics Factory, to analyze and evaluate the green indexes (including green rate and green area) and green ecosystem performance (including absorption CO2 and release O2, amount of water transpiration and heat absorption during transpiration and absorption dust), the plants'species and frequency, plants'structure (including the comparison of tall tree, bush and grass, the species, installation ways and frequency of tall trees on the roads and installation ways in flower terraces) and the choice of plants (including resistance and absorption pollution).3. Constructed the evaluation index system of produce green areas in petroleum chemistry industry areas. Through distributing a lot of questionnaires, the paper got the importance of every index and its satisfactory.4. The ways of green construction in petroleum chemistry industry areas was discussed by being divided into three systems, shelter forest system, factory green system and residence green system, to provide consultation for green constructor.Finally, the paper summed up the former conclusions, discussed the greening indexes, found the ways to solve the problems, and suggested that we should intensify and accomplish the researches about petroleum chemistry industry areas. |
