Ecological Environment


   Tai’an is located in the temperate continental semi-humid monsoon climate zone.It has distinctive four seasons. It is dry and windy in spring, hot and rainy in summer, sunny and cool in autumn, cold and little snowy in winter. The annual average solar radiation is about 121.58 kilocalorie/ s.q cm with the changes between 112 and 131 kilocalorie/ s.q cm. It has the most solar radiation in may and least in December. The solar energy that can be used in Tai’an is about 10.2 billion kilocalorie/ hectare during March to November when the crops grow.
   With the percentage of sunshine around 58%, the annual sunlight duration in Tai’an is about 2627.1 hours with changes from 2342.3 to 3413.5 hours. It has most sunshine from May to June when the wheat is milking with average monthly sunshine duration of about 268 hours, which is good for the growth of wheat.The annual average temperature in Tai’an is about 12.9℃ with the highest temperature of 26.4 ℃ in July and the lowest temperature of -2.6℃ in January. Its good temperature can meet the need of double cropping or triple cropping a year.
  The annual average precipitation is about 687 millimeter in the city. For the influence of monsoon climate,the annual precipitation fluctuates greatly with maximum precipitation of 1498 millimeter and the minimum precipitation of 199 millimeter. Because of the landform, the rainfall in east is more than the west and the mountain area than the plain.And the yearly rainfall is not balanced with the most rain in summer and the least in winter. There are most rainfall in July with the percentage of 32.1% and the least in January with the percentage of 0.96%.
   There are also some microclimate zones in Tai’an because of the landform and regional disparity. On the top area of Mount Tai,the annual temperature is only 5.2℃ while the annual precipitation reaches 1163.8 millimeter. And there are high temperature regions around Zulai Mountain and the Chaiwen River with the annual temperature above 14℃, which reaches the temperature of subtropical zones. Many famous special plants grow in these different microclimate zones.

   Tai’an got good results on energy-saving and cost-reducing. On the first half year of 2012, the energy consumption per 10 thousand yuan GDP fell 4.2% on year-on-year basis and the power consumption per 10 thousand yuan GDP fell 9.0%. The industrial energy consumption of the enterprises above the designated size was up 4.6% from a year earlier.The added value of the five high energy-consuming industries that is coal, coking, chemistry, nonmental, nonferrous mental was up 6.0% which was 6.7% percent below the industrial growth rate of the enterprises above the designated size.The ratio of the energy processing ans conversion of the enterprises above the designated size reached 87.4% with an increase of 4.8%. Among the 31 kinds of products that the key energy consumption enterprises investigated on the energy consumption per unit product, 19 kinds of the products fell 61.3%.

   The energy conservation on construction area made steady headway. The close management for the energy-saving construction has been carried out. It reached 100% on the prohibition of the solid clay brick for the construction on the town planning area. The implementation rate of the energy-saving standard of the new construction projects reached 100%. 1.2 billion sample blocks of new wall material were used for the whole year which saved 127 hectare lands and 63 thousand ton coal.The solar water heater, solar street lamp and gas are popular in the new rural communities which promotes the development of energy-saving in rural areas.

   It got achievements on the land saving and intensive use. In 2012, Tai’an reported to the State Council and Shandong Provincial People’s Government the use of construction lands of 1533 hectare, among which 1467 hectare lands were newly added construction lands and 66 hectare lands were the stock lands. This ensured the construction lands in the city can meet all the needs. There were about 1667 hectare reclamation lands and 800 hectare newly added farmlands. The agricultural lands got effective protection and use.

   The environment quality has been improved. In 2012, there were 254 days with good air quality in the city. The permanganate index and the annual concentration of ammonia nitrogen of the Wangtai Bridge fracture surface, Dawen River and the middle of Dongping lake conformed to the III standard of Environmental Quality Standard for Surface Water and the fracture surface of Houdian, Guangfu River conformed to the IV standard of Environmental Quality Standard for Surface Water. In 2012, there were 76 projects of chemical oxygen demand and nitric oxide emission reduction with the reduction of 15607 ton sulfur dioxide and 54 ton nitric oxide. Now there are 6 motor vehicle environmental detection institutions in the city. All the motor vehicles of the city must take the environmental detection and get the mark. 1.5 billion qualified environmental mark have been granted in the city.

   We made new progress for the building of ecological city. There are 6 natural protection zones with the area of 55 thousand hectare. The forest coverage rate of the city is 38.5% with an increase of 0.7%. There were 51 towns in the city that were named ecological towns, among which 7 were national ecological towns and 25 were provincial towns. 163 green schools were built, among which 1 was national green school and 48 were provincial schools. The green coverage rate of the built up area is 44%. The city passed the reexamination of the Chinese Habitat City, National Model City for Environmental Protection and National Hygiene City.
