Study On Sustainable Development Level Of Chemical Industry Park In Guanzhong Area

In recent years,the situation of environmental risk caused by industrial layout,development status and industrial accidents in chemical industrial park is becoming more and more serious.The sustainable development evaluation of the park is the basis for formulating the sustainable development of the park.At present,the domestic sustainable development evaluation is still in the initial stage.On the on hand,it deliberately increases the number of indicators in order to pursue the completeness of the index system,which makes the index system too large.On the other hand,lack of scientific and effective index screening methods,mostly rely on the subjective experience of evaluators.The above two problems are the main reason that the evaluation system cannot reflect the sustainable development level of the park.Based on the chemical industry park in Guanzhong area of Shaanxi Province as the research object,with reference to the evaluation standards for the relocation of chemical industry park that can carry hazardous chemicals issued by Shaanxi Province,combined with the overall planning of the park and the environmental assessment The report summarizes a set of indicators system applied to the sustainable development of Shaanxi chemical industry park.The index system includes 6 first level indexes and 43 second level indexes.The weights of X1,X2,X3 and X4 are 0.0523,0.0294,0.0162 and0.081,respectively.The weights of the first level indexes are 0.081,0.0972,0.4694,0.0842,0.2386 and 0.0196.According to the evaluation index system and the calculated index weight value,the evaluation model of sustainable development level of chemical industry park is constructed.In this paper,nine chemical industry parks in Guanzhong are taken as anexample for empirical analysis: Z-score method is used to standardize the secondary index data collected,and the standardized values of 10 negative three-level indexes are adjusted by sign;multi-objective linear weighted sum method is used to calculate the sustainable development level evaluation score of Guanzhong chemical industry Park,and the evaluation score is obtained through the evaluation score out:(1)The comprehensive scores of sustainable development level of chemical industry park in Guanzhong region of Shaanxi Province from high to low are as follows: Weibei coal and chemical industry park(77.0),Han Cheng economic and Technological Development Zone(75.3),Fengxiang Changqing Industrial Park(71.7),Fuping Zhuangli Industrial Park(64.8),Binxian Xinmin chemical park(64.2),Changwu Wulipu Industrial Park(62.5),Huazhou Industrial Park,Chengcheng Industrial Park(50.5)and Xingping Industrial Park(49.8).(2)According to the horizontal evaluation and analysis,the principal problems of the chemical parks in Guanzhong are as follows: the natural resource ratio of the chemical park is extremely unbalanced;the level of economic development of the chemical park is uneven;the rate of infrastructure construction in the park is not high;the level of green management and safety production in the park is not high;the supervision and management of the chemical park are not strict and in place.(3)From the analysis of the indicators at the first level,it can be concluded that: in the aspect of social economy,the scale of the park lead to the uneven level of social economy;the land carrying capacity and atmospheric capacity of the Han Cheng economic and Technological Development zone are limited;while the land carrying capacity,atmospheric environmental capacity and water environmental capacity of the Bin Xian Xin Min chemical park are lowest;The impact index mainly refers to the discharge and treatment rate of the three Wastes,the main reason being the low infrastructure construction rate of waste water and waste gas,and it is suggested that each park should speed up the construction of infrastructure facilities,the main impact indicators are the reuse rate of reclaimed water,energy consumption and water consumption;in terms of safe production,the main impact indicators are the rate of issuance of discharge permits and the rate of implement;and in terms of green management,the main impact indicator is the rate of on-line EnvironmentalMonitoring System Networking.
