Brief Introduction
I. Main Contents
This chapter
contains information that reflects the development of environment protection in
The contents aim to
present total water resources,
water supply and utilization, discharge and treatment of industrial and other
waste water; urban air quality, emission and treatment of waste gas;
production, treatment and utilization of industrial solid wastes, collection
and disposal of consumption wastes in cities; national monitoring of road traffic
noise and urban environmental noise in key cities; land use, change in
cultivated land and forest resources, afforestation and forest protection;
incidences of geological, seismic, marine
and forest disasters, environmental pollution and destruction incidents;
investment in environment pollution treatment, etc.
II.
Sources of Data
Data on
environmental pollution and treatment, pollutants from consumption, acoustic
environment and on investment in the treatment of industrial pollution are provided by the State Environment Protection
Administration.
Data
on water resources, collection and disposal of
urban consumption wastes, land use and change in
cultivated land, forest resources, marine disasters, etc. are provided
respectively by Ministry of Water Resources, Ministry of Construction, Ministry
of Land and Resources, State Forestry Administration and State Oceanic
Administration.
III.
Scope of Statistics and Methods of Survey
1) Scope of statistics:
industrial enterprises, urban living and other urban units which discharge
pollutants.
2) Survey methods
for discharge and treatment of industrial pollutants: comprehensive survey is
conducted on all key industrial enterprises, while overall estimation is
carried out for non-key enterprises. Key enterprises refer to those enterprises
which account for more than 85% of all pollutants discharged in the region. For
non-key enterprises the discharge of which is less than 15% of the total of the
region, estimation is made by the volume of their discharge of waste water,
chemical oxygen demand, ammonia and nitrogen, sulphur dioxide, industrial soot
and dust, and solid wastes. Data on discharge of pollutants of key and non-key
enterprises make up the total discharge of the region.
3)
Data on pollution from consumption and other sources are estimated using
relevant statistics and technical parameters.
