Brief Introduction

I. Main Contents

This chapter contains information that reflects the development of environment protection in China. The main contents are on the fresh water environment, the atmospheric environment, solid wastes, acoustic environment, ecological environment, natural disasters and environmental pollution and investment in treatment of such.

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.
