Explanatory Notes on Main Statistical Indicators

 

Average Temperature  Temperature refers to the air temperature. China uses centigrade as the unit. The thermometry used for weather observation is put in a breezy shutter, which is 1.5 meters high from the ground. Therefore, the commonly used temperature refers to the temperature in the breezy shutter 1.5 meters away from the ground. The calculation method is as follows:

Monthly average temperature is the summation of average daily temperature of one month divided by the actual days of that particular month.

Annual average temperature is the summation of monthly average of a year divided by 12 months.

Relative Humidity   refers to the ratio of actual water vapour pressure to the saturation water vapour pressure under the current temperature. The calculation method of average relative humidity is the same as that of average temperature . 

Volume of Precipitation  refers to the deepness of liquid state or solid state (thawed) water falling from the sky to the ground that has not been evaporated, infiltrated or run off. The calculation method is as follows:

Monthly precipitation is the summation of daily precipitation of a month.

Annual precipitation is the summation of 12 months precipitation of a year.

Sunshine Hours   refers to the actual hours of sun irradiating the earth. The calculation method is the same as that of the precipitation.

Forest Area  refers to the area of trees and bamboo grow with canopy density above 0.2, the area of shrubby tree according to regulations of the government, the area of forest land inside farm land and the area of trees planted by the side of villages, farm houses and along roads and rivers.

Forest Coverage Rate  Taking the administrative jurisdiction as the unit, the percentage of area of afforested land to the area of total land.  The formula for calculating forest coverage rate is as follows:

Total Standing Stock Volume  refers to the total stock volume of trees growing in land, including trees in forest, trees in sparse forest, scattered trees and trees planted by the side of villages, farm houses and along roads and rivers.

Stock Volume of Forest  refers to total stock volume of wood growing in forest area, which shows the total size and level of forest resources of a country or a region.

Manual Planting  refers to technical measures of sowing, planting seedlings and divided transplanting on land suitable for afforestation, including barren hills, idle land, sand dunes, non-timber forest land, woodland and ��grain for green�� land to increase vegetation coverage rate of forests.

Mineral Resources  refer to useful minerals, with solid state, liquid state, gaseity, due to the geological process. Minerals are important natural resources, and important material base for social development.

Ensured Mineral Reserves  refer to the actual mineral reserves, which equal to the proven mineral reserves (including industrial reserves and prospective reserves) minus extracted parts and underground losses.

Common Industrial Solid Wastes Produced refers to the industrial solid wastes that are not listed in the ��National Catalogue of Hazardous Wastes��, or not regarded as hazardous according to the national hazardous waste identification standards (GB5085), solid waste-Extraction procedure for leaching toxicity (GB5086) and solid waste-Extraction procedure for leaching toxicity (GB/T 15555). The calculation formula is as followed:

Common Industrial Solid Wastes Produced = (common industrial solid wastes utilized �C the proportion of utilized stock of previous years) + common industrial solid waste stock + (common industrial solid wastes disposed �C the proportion of disposed stock of previous years) + common industrial solid wastes discharged.

Common Industrial Solid Wastes Comprehensively Utilized 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) during the report period, e.g. being used as agricultural fertilizers, building materials or as material for paving road. Examples of such utilizations include fertilizers, building materials and road materials. The information shall be collected by the producing units of the wastes.

Common Industrial Solid Wastes Disposed refers to the quantity of industrial solid wastes which are burnt or specially disposed using other methods to alter the physical, chemical and biological properties and thus to reduce or eliminate the hazard, or placed ultimately in the sites meeting the requirements for environmental protection during the report period.

Stock of Common Industrial Solid Wastes refers to the volume of solid wastes placed in special facilities or special sites by enterprises for purposes of utilization or disposal during the report period. The sites or facilities should take measures against dispersion, loss, seepage, and air and water contamination.

Common Industrial Solid Wastes Discharged refers to the volume of industrial solid wastes dumped or discharged by producing enterprises to disposal facilities or to other sites.

Hazardous Wastes Produced refers to the volume of actual hazardous wastes produced by surveyed samples throughout the year of the survey. Hazardous waste refers to those included in the national hazardous wastes catalogue or specified as any one of the following properties in light of the national hazardous wastes identification standards and methods: explosive, ignitable, oxidizable, toxic, corrosive or liable to cause infectious diseases or lead to other dangers. The report of this indicator should follow the ��National Catalogue of Hazardous Wastes�� (the NO.1 Ministry Order in 2008 by the Ministry of Environment Protection and National Development and Reform Commission).

Hazardous Wastes Utilized refers to the volume of hazardous wastes that are used to extract materials for raw materials or fuel throughout the year of the survey, including those utilized by the producing enterprise and those provided to other enterprises for utilization.

Hazardous Wastes Disposed refers to the quantity of hazardous wastes which are burnt or specially disposed using other methods to alter the physical, chemical and biological properties and thus to reduce or eliminate the hazard, or placed ultimately in the sites meeting the requirements for environmental protection during the report period.

Stock of Hazardous Wastes refers to the volume of hazardous wastes specially packaged and placed in special facilities or special sites by enterprises. The special stock facilities should  meet the requirements set in relevant environment protection laws and regulations such as ��Pollution Control Standards for Hazardous Waste Stock�� (GB18597-2001) in regard to package of hazardous waste, location, design, safety, monitoring and shutdown, and take measures against dispersion, loss, seepage, and air and water contamination.
