environmental risk source, and then work out the monitor-
ing and management measures against each grade of
environmental risk source, especially the major ones. In
this way, the environmental risk can be reduced from the
source,
To comprehensively master the spatial distribution and
hazard level of the fixed environmental risk sources of
China, identify the major risk sources, and provide basic
information for the establishment of China’s regional en-
vironmental risk source files and database, the Ministry
of Environmental Protection, in May 2009, carried out
the environmental risk and chemicals inspection on the
enterprises of 3 national key sectors (petroleum process-
ing and coking, chemical material and product manufac-
ture and medicine manufacturing), totaling 10 industries
and 35 sub-industries. In a sense, the enterprises of 35
sub-industries involved in this inspection belongs to the
environmental risk sources defined according to the
industry characteristics classification, with each enterprise
equivalent to one environmental risk source. However,
the relevant research by Wei Keji et al. (2010) summa-
rizes the classification of environmental risk source into
the followings: the environmental sufferer-based classifi-
cation, such as the water environment risk source, atmos-
pheric environment risk source and soil environment risk
source; the material state-based classification, such as the
gaseous environment risk source, liquid environment risk
source and solid environment risk source; the transmis-
sion route-based classification. Wen Lili et al. (2010)
presented the design principle of major environmental
risk source monitoring system based on the classification
into liquid source, solid source and mobile source.
The environmental risk source gradation management
aims to effectively avoid risk of each grade of environ-
ment risk of the same category; the risk source gradation
management can save the management cost and shorten
the emergency response time, therefore enhancing the
efficiency of risk management. Wei Keji (2010) built the
environment hazard index according to the hazard of risk
source to water, atmosphere and soil to divide the risk
sources into four grades, and then presented the identifi-
cation standard system of major environmental risk
source according to the said gradation.
Many industries in the various categories of national
economy have the environmental risk and it is hard to
make the uniform classification and assessment, therefore,
the chemical raw materials/products manufacturing in-
dustry or the chemical industry park shall be chosen for
the initial research on the environmental risk source assess-
ment and gradation management standards, and we shall
work out the prevention and early warning measures
against the major risk source of such industry in aspect of
technology transformation, equipment elimination, per-
sonnel training, etc. with a purpose to eliminate the major
petrochemical environmental pollution accidents at their
early stage.
As to the VOCs pollution risk, source tracing and
characteristics of industrial VOCs emissions in China
should pay more attention to the production of VOCs, the
storage and transport, industrial processes using VOCs as
raw materials and use of VOCs-containing products.
3. Research on Vulnerability of
Environmental Risk Targets
From the point of region, the environmental risk sufferer
is a compound system including the social economy, natural
ecology and other factors, so the object suffering the sud-
den environmental pollution accident risk includes the
social economy and ecosystem, and the integrated vul-
nerability of risk sufferer is composed of the vulnerabil-
ity of social economy and that of ecosystem.
For the social economic system, we mainly consider
the scale of regional population and economy, the re-
gional accident prevention and emergency measures, the
scale of other infrastructures and so on; for the natural
ecosystem, we mainly consider the sensitive ecosystem,
including the ecosystem of drinking water source area,
natural reserve and wetland.
During the “12th Five-Year Plan” period, we shall re-
search the vulnerability of social environmental risk suf-
ferer through such aspects as population density, the
density of hospital and urban lifeline, regional early-
warning capacity, proportion of public education in GDP,
number of hospital bed per 10,000 persons, per capita
GDP, regional emergency evacuation capacity, sudden
environmental pollution accident response capacity and
prevention capacity, etc. and figure out the pertinent and
practical measures to isolate risks or enhance the risk
resistance capacity for the much vulnerable social risk
sufferers; the research on vulnerability of natural eco-
logical environmental risk suffer shall be carried out
through the sensitivity and adaptability of regional eco-
system (including water area ratio, regional environ-
mental improvement index, river regulation investment
ratio, standard discharge rate of industrial wastewater)
and related to the regional emergency monitoring and
response to effectively reduce the damage caused by the
ecosystem pollution accident.
4. Environmental Risk Zoning Management
At present, the Emergency Response Law of the People’s
Republic of China is lack of the relevant implementing
rules, there is no adequate legal basis for implementation
and the relevant supporting policies are not formulated
yet, so there is no pertinent guide on the prevention and
management of environment risk. During the “12th Five-
Year Plan” period, we shall, based on the classification
