As for the integrated pollution index, the pollution is more serious in the Guangzhou, Zhongshan and Dongguan sections, while Huizhou and Jieyang have a better seawater quality.

Ecological Environment

a. Forest

By the end of 2001, the area of provincial forestry lands is 10.233milliom hectares, the area of woodlands is 7.089 million hectares and the area of ecological commonweal woodland is 3.573 million hectares, which stands 33% of woodlands area.

In the whole year, had completed the forest plantation on 57.56 thousands of hectares deserted mountains and deserts, 68.92 thousands hectares of renovation of traced land and 43.5 thousands hectares of reconstruction of low-productive woods area. Number of voluntary tree planted is 90.03 million trunks

The total woods provincial production is 1741 m3, the total woods wastage is 675m3;the total amount of growing stock is 33949m3, is 1092m3 more than last year. Forestry coverage is 57.2%, 0.1% more than last year.

In the whole year, number of forest fire occurred is 1677 times, among that is 40 times fire alter, normal forest fire 127 times, overshoot area is 2525 hectares, suffered injured forest area 965 hectares.

b. Urban Gardening and Virescence

By the end of 2001, greenery coverage of urban construction region is 33.2 %, 0.68 % more than last year; percentage of greenbelt in urban construction region is 29.73%, 0.77 % higher than data of 2001; the average urban public greenbelt per person is7.64 m2, 0.1 % less than that of 2001.

c. Land

By the end of 2002, provincial plantation area is 3068.6 thousand hectares, 2% less than last year; basic farmland conservation area is 2849.3 thousands hectares 2.8% more than last year. In the same year, the area of soil erosion control is 60 thousand hectares. By the end of the year, there is still 1052 thousand hectares of soil erosion area. The same year, re-cultivate area of mining lands is 1084.42hectares, about 28.5 % of the 3799.87 hectares promised re-cultivate lands.

Radiation Environment

The provincial nuclear station emergency response and the surrounding environment of nuclear power station is good, the radiation monitoring system is operating well, and the nuclear power station emergency response work is carrying out normally.

The No.2 unit of Da Yawan Nuclear Power Station and the No.1 unit of LinAo Nuclear Power Station are under good operation condition. The annual radioactivity nuclide emission is under national limit, is the lowest level in the past years. The environmental radioactivity level has no changes, compare with the condition before the nuclear station is operated.

As for the radiation monitoring done to the surrounding of the radiation waste storage( including ¦Ã radiation measurement, aerosol, soil, underground water, ground water, concentration of radon) showed no obvious changes occurred to the surrounding environmental radioactivity level.

The Environmental electromagnetism radiation mainly comes from communications, radio and television injection station and electrical transmission facilities. The monitoring results showed that provincial radiation level around most of the electromagnetism source are within national standard limit, belongs to positive wave communication injection station high level electromagnetism radiation level. Some of measurement points that are located near antenna are beyond national standards limit, and further supervision is needed. Inside the high-voltage electricity transmission and transformer system, the power frequency electric field intensity near the major transformer belongs to high level; some of the measurement points are beyond national limit.

Ecological Conservation

a. Natural Preservation Region

By the end of 2002, Guangdong has set up 198 Natural Preservation Region, total area of 3.0087 million hectare, including land area 766.4thousand hectare, which is 4.31% of provincial land area.

b. Ecological Demonstrative Region

Deepen in the construction of ecological demonstrative region. Has set up 11 national ecological demonstrative region experimental units, including Zhuhai, Zengcheng, Longmen, Zhanjiang, Lianjiang, Zhongshan, Nanao, Shixing, Lianping, Xuwen and Jiexi. Guangdong EPB has examined and named 39 provincial ecological demonstrative regions. Till now, 106 provincial ecological demonstrative regions have been named, including 16 ecological demonstrative town, 53 ecological demonstrative villages, 10 ecological demonstrative farms and 27 ecological demonstrative gardens.

c. Control of area source pollution

Carry out the <Decision about speed up the development in mountainous district > issued by the provincial government, emphasize on the protection of drinking water source, agriculture production and natural resources. Increase the degree in the supervision management and pollution control in rural pollution source. Strengthen the management in birds and animal breeding industry, organized the control of breeding farms located in key river basin, and entirely demolished the breeding farms located in the drinking water source region.
