Developed Areas
refer to the land in administrative areas having been developed concentratedly with municipal public facilities. For core
city, developed areas include concentrated areas and decentralized areas,
having basic perfect municipal public facilities; for the city with several
towns, developed areas are composed of several concentrated areas with
municipal public facilities. Therefore, the scope of developed areas refers to
actual construction land of a city.
Water Supply
refers to gross water supply by supply systems from sources to consumers,
including losses during distribution.
Waste Water Discharged by Industry
refers to the
volume of waste water discharged by industrial enterprises through all their
outlets, including waste water from production process, directly cooled water,
groundwater from mining wells which does not meet discharge standards and
sewage from households mixed with waste water produced by industrial
activities, but excluding indirectly cooled water discharged (It should be
included if the discharge is not separated with waste water).
Ratio of Reaching the Standard of
Industrial Waste Water
refers to percentage of industrial waste water
meeting discharge standards over total industrial waste water discharge. It is
calculated as:
|
Ratio of Reaching the Standard of
Industrial Waste Water = |
Industrial Waste Water Meeting Discharge Standards |
��100% |
|
Total Industrial Waste Water Discharge |
Industrial Waste Gas
Emission
refers to discharge into atmosphere of waste air containing pollutants generated
from fuel burning and production process in enterprises within a given period
of time. It is calculated at standard status (273K, 101325Pa) as:
Industrial Waste Gas Emission = Emission
through Fuel Burning +
Emission through Production Process
Industrial Dust Emission
refers to
volume of dust emitted by production process of enterprises and suspended in the
air for a given period of time, including dust from refractory material of iron
and steel works, dust from coke-screening systems and sintering machines of
coke plants, dust from lime kilns and dust from cement production in building
material enterprises, but excluding soot and dust emitted from power plants.
Industrial Waste Residue Produced
refers to total
volume of solid, semi-solid and high concentration liquid residues produced by
industrial enterprises from production process in a given period of time,
including hazardous wastes, slag, coal ash, gangue, tailings, radioactive
residues and other wastes, but excluding stones stripped or dug out in mining
(gangue and acid or alkaline stones not included). A stone is acid or alkaline
depending on the pH value of the water below 4 or above 10.5 when the stone is
in, or soaked by, the water.
Comprehensive Utilization of Industrial
Waste Residue
refers to
volume of solid wastes from which useful materials can be extracted or which
can be converted into usable resources, energy or other materials by means of
reclamation, processing, recycling and exchange (including utilizing in the
year the stocks of industrial solid wastes of the previous year). Examples of
such utilizations include fertilizers, building materials and road materials.
Ratio of Comprehensive Using Industrial
Waste Residue
refers to the percentage of industrial solid wastes
utilized over industrial solid wastes produced (including stocks of the
previous years). It is calculated as:
|
Ratio of Comprehensive Using Industrial Waste Residue = |
Volume of Industrial Solid Wastes Utilized |
��100% |
|
Industrial Solid Wastes Produced+Stock
of Previous Years |
Level of Equivalent Noise (LEQ)
refer to the A sound
pressure of a continuous steady state sound, in the specified time interval
with the same mean square A sound pressure as the time variant noise. This
sound level of a continuous steady state sound is the equivalent sound level of
the time variant noise. The smaller of the value of noise equivalent sound
level (dB), the better.
Natural Reserves
refer to certain areas of land, waters or sea that are representative in
natural ecological systems, or are natural habitats for rare or endangered wild
animals or plants, or water conservation zones, or the location of important
natural or historic relics, which are demarked by law and put under special
protection and management. Natural reserves are designated by the formal
approval of governments at and above county level (including those approved by
relevant departments or ��revolutionary committees�� before 1980). Scenic spots
and cultural preservation zones are not included.
