On the State of the Environment In China
Climate and Natural Disasters
Basic Climate Situation In 2002, the temperature in most parts of the country was higher than that in normal years. The precipitation was above or on the par of that in normal years. Different types of meteorological disasters and abnormal climate occurred during the year. According to the statistics on the area of crops hit by disasters nationwide, drought and flood were still main climatic disasters with the stricken area exceeding three fourth of the total area hit by disasters. The loss caused by climatic disasters was moderate to serious this year.
Distribution of Precipitation In 2002, the precipitation was larger than that in normal years. The annual precipitation in the nation had unbalanced space-time allocation and was 33.1 mm higher than that in normal years. Different degrees of drought occurred in Yellow River and Huai River Basin, northern part, northeast, northwest, and southern part of China. Certain degree of flood also occurred in some areas of southeast, south, southwest and north- west part of China.
Distribution of Precipitation in the Country in 2002
Temperature Allocation In 2002, the temperature in most parts of China was higher than that in normal years. In winter ( from December 2002 to February, 2002 ), average temperature nationwide was 2°C higher than that in normal years. This winter was considered as the second warmest in the past 50 years. In spring ( from March to May), the temperature in most parts of China was higher by 1-2°C compared with that in normal years. In Summer (from June to August), the average temperature in most parts of China was normal or a little bit higher. The temperature in north-west and north part of China was higher by 1-2°C. In Autumn (from September to November), the temperature in most parts of China was almost the same as that in normal years.
Climatic Disasters (Drought) In 2002, the precipitation from January to March in northern and southern part of China was reduced by 40%. The temperature was continuously abnormally high at the same period. The area hit by drought covered most parts of north, middle and west part of northeast, north part of Yellow River and Huai River, east part of northwest and some parts of south and southwest. According to the statistics at the end of March, the area hit by drought and water shortage in the nation was 21 million hectares. 15.9 million rural people suffered from temporary shortage of drinking water. Some cities and towns above county level in 24 provinces (autonomous regions and municipalities) lacked water resources. (Rainstorm) From the end of April, 2002, to the middle of May, overcast and rainy weather continued in the middle and lower reaches of Yangtze River. Heavy rain or rainstorm occurred in parts of the region. The precipitation was around 200 to 500 mm. The water level in the tributaries of Dongting Lake and Boyang Lake was even above alarming water lever for a time. There were obvious spring floods. Water logging occurred in some areas. Rainy season started early in northern part of China with moderate to heavy rain, or even rainstorm from west to east in early and middle of June. Floods, mud-rock flow and landslide disasters occurred in certain parts of Shaanxi, Ningxia, Gansu, Xinjiang, Hebei and other provinces. In Foping county of Shaanxi province, the mortality from these disasters was 132. At the end of October, heavy rain to rainstorm occurred in Nanling and Wuyi Mountain, which was considered as unusual late autumn floods. (Tropical Windstorm) In 2002, 26 cases of tropical windstorm occurred in northwestern Pacific and South China Sea. Among those, 17 cases were further developed to be typhoon. Six cases landed in China. The number of cases landed was less than that in normal years. The intensity was weaker, therefore, the losses was less serious compared with that in previous years. (Sandstorm) In the spring of 2002, 12 cases of sandstorm (eight cases were generated from Mongolia) occurred in the country. These cases were characterized as strong intensity, wide scale of influence, and the occurrence being centralized in certain period.
Earthquake Disasters In 2002,
there were 29 earthquakes in China registered as 5 scales of magnitude
above. Among that, there were 25 earthquakes with 5 scales of magnitude,
2 earthquakes with 6 scales of magnitude and 2 earthquakes with 7 scales
of magnitude. 19 earthquakes occurred in Taiwan, 1 case in East China
Sea and 9 cases in Chinese mainland.

Geological Disasters In 2002, there
were 40246 cases of various types of geological disasters in the country,
causing the death of 853 people, disappearance of 109 people and injury
of 1797 people. The direct economic loss was 5.1 billion Yuan.
