Explanatory Notes on Main
Statistical Indicators
Production
Capacity of Water Supply refers to the designed
comprehensive production capacity of water facilities, covering the 4 links of
water collection, purification, conveyance, and outflow through trunk
pipelines. Increase capacity through transformation and
innovation projects are included as well. The capacity is determined
mainly on the weakest of the above-mentioned 4 links.
Length
of Water Supply Pipelines at the Year-end refers to
the total length of all the pipelines between the water pumps and the user water
meters, excluding pipelines newly installed but not used yet.
Annual
Volume of Water Supply refers to the total volume
of water supplied by water-works (units) during the reference period, including
both the effective water supply and loss during the water supply.
Consumption
of Water for Residential Use refers to the water
consumption of households for daily life and the water consumption of public
service facilities. The latter refers to water consumption for urban public
services, including the consumption of government agencies and public
institutions, military barracks, public facilities, wholesale and retail
outlets, restaurants, hotels, and other units providing public services.
Household water consumption refers to consumption of water for daily life of
all households in the boundary of cities, including households of urban
residents and farmers, and public water supply stations.
Percentage
of Urban Population with Access to Tap Water refers
to the ratio of the urban non-agricultural population (excluing
temporary and mobile population) with access to tap water to the total urban
non-agricultural population.The formula is:
Percentage of Population with Access to Tap
Water ＝Urban Non-agricultural Population
with Access to Tap Water ÷Urban Non-agricultural Population×100%
Production
Capacity of Gaswork Gas
refers to the actual comprehensive production capaCity
of the urban gasworks in gas generation, purification and delivery.
Length
of Gas Pipelines refers to the total length of
pipelines between the outlet of the compressor, blower or gas tank and the gas
meters of users.
Volume
of Gas Supply refers to the total volume of gas
sold to users in a year, including the volume for industrial use, residential
use and other uses.
Percentage
of Urban Population with Access to Gas refers to
the ratio of the urban non-agricultural population with access to gas
(including gas, liquefied petroleum gas and natural gas) to the urban
non-agricultural population(excluding temporary and
mobile population). The formula is:
Percentage of Population with Access to Gas
=Urban Non-agricultural Population with Access to Gas÷Urban
Non-agricultural Population×100%
Heating
Capacity in Urban Area refers to the capaCity of hourly supply of steam and hot water to cities
by thermal power plants,heating
corporations and centralized heating boiler rooms which meet certain standard.
Quantity
of Heat Supplied in Urban Area refers to the total
quantity of heat from steam and hot water supplied to cities every year by
thermal power plants,heating
corporations and centralized heating boiler rooms which meet certain standard.
Length
of Heating Pipelines refers to the total length of
pipelines for centralized supply of steam and hot water from the thermal power plants,heating corporations and
centralized heating boiler rooms which meet certain standard to the users.
Length
of Paved Roads at the Year-end refers to the length
of roads with a paved surface, and with a width of more than 3-5 meters,
including high quality,medium
quality and ordinary roads.
Urban
Bridges refer to bridges over river courses, great
separated junctions and overpasses in urban areas.Permanent
bridges and semi-permanent bridges are included.Temporary
bridges,railway bridges and
culverts are excluded.
Length
of Urban Sewage Pipes refers to the total length of
general drainage, trunks. branch and blind drainage,
inspection wells, connection wells, inlets and outlets, etc.
Daily
Disposal Capacity of Urban Sewage refers to the
designed 24 hour capaCity of sewage disposal at the
sewage treatment works.
Number
of Public Vehicles (Buses and Trolley buses) at the Year-end refers to the total number of operational buses available at the
year-end, including the year-end operational vehicles and vehicles in stock.Non-operational vehicles such as stringing cars,tank cars,machine shop cars,trucks and other special vehicles and the borrowed
passenger vehicles are excluded.
Area
of Urban Gardens and Green Areas refers to the
total area of urban public green land,special
green land,production green land,protection
green land and suburban scenic spots.
Public
Green Area refers to green areas of various parks,
zoos, botanical gardens, cemeteries, amusement parks, tree-flanked boulevards greenland squares for tourism and relaxing.Areas with trees planted along-side the streets
and boulevards are excluded.
