Based on historical documents, modern survey and statistics, as well as the result of predecessor studies, the trend and main process of forest dynamics are recognized. The forest area and forest coverage rates for each province of China from 1700 to 1949 are es- timated backward by every 50 years. Linking the result with modern National Forest Inventory data, the spatial-temporal dynamics of Chinese forest in recent 300 years (AD 1700–1998) is quantitatively analyzed. The study shows that in recent 300 years, the forest area in current territory of China has declined by 0.95×108 hm2 (or 9.2% of the coverage rate) in total, with a trend of decrease and recovery. Before the 1960s, there was a trend of accelerated de- scending. The forest area was reduced by 1.66×108 hm2 (or 17% of the coverage rate) in 260 years. While after the 1960s, there has been a rapid increase. The forest area increased by 0.7×108 hm2 (or 8% of the coverage rate) in 40 years. The study also shows that there is a significant spatial difference in the dynamics of forest. The amplitudes of increasing and de- creasing in western China are both smaller than the ones in eastern China. During the rapid declining period from 1700 to 1949, the most serious decrease appeared in the Northeast, the Southwest and the Southeast, where the coverage rate in most provinces dropped over 20%. In Heilongjiang Province, the coverage rate dropped by 50%. In Jilin Province, it dropped by 36%. In Sichuan Province and Chongqing Municipality, it dropped by 42%. In Yunnan Prov- ince, it dropped by 35%. During the recovery period 1949–1998, the western provinces, mu- nicipality and autonomous regions, including Ningxia, Gansu, Inner Mongolia, Si- chuan–Chongqing, Yunnan, Tibet, Xinjiang and Qinghai, etc, the increase rates are all below 5%, while the eastern provinces, municipality and autonomous regions (except Heilongjiang, Hubei, Jiangsu–Shanghai) have achieved an increase over 5%, among which the Guang- dong–Hainan, Guangxi, Anhui, Beijing–Tianjin–Hebei, Shandong, Henan, Zhejiang, and Fu- jian have an increase over 10%.

A history of long and effortless success can be a dreadful handicap,but,if properly handled,it may become a driving force.When the United States entered just such a glowing period after the end of the Second World War,it had a market eight times larger than any competitor ,giving its industries unparalleled economies of scale.Its scientists were the world's best,its workers the most skilled.American and Americans were prosperous beyongd the dreams of the Europeans and Asians whose economeics the war had destroyed.
It was inevitable that this primacy should have narrowed as other countries grew richer.Just as inevitably,the retreat from predominace proved painful.By the mid 1980s Americans had found themselves at a losss over their fading industrial competitiveness.Some huge American industries,such as consumer electronics,hand shrunk or vanished in the face of foreign competitiong.By 1987 there was only one American television maker left,Zenith.(Now there is none :Zenith was bought by SouthKorea'sLGElectronics in July.)Foreign made cars and textiles were sweeeping into the domestic market.America's machine-tool industry was on the ropes.For a while it looked as though the makeing of semiconductors,whidh America had invented and which sat at the heart of the new computer age,was going to be the next caualty.
All of this caused a crisis of confidenc.Americans stopped taking prosperity ofr granted .They began to believe that their way of doing business was failing,and that their incomes would therefore shourtly begin to fall as well .The mind -1980s brought one inquiry after another into the causes ofAmerica's in dustrial decline.Thir sometimes sensational findings were filled with warnings about the growing competitiong from overseas.
How things have changed!I1995 the United States can look back on five years of solid growth while Japan has been struggling.Few Americans attribute this Self doubt has yielded to blind pride.American industry has changed its structure ,has gone on a diet ,has learnt to be more quik witted,according to Richard Cavanagh,executive dean of Harvards Kennedy School of Government.'It makes me proud to be an American just to see how our businesses are improving theirproductivity,says Stephen Moore of the Cato Institute ,a think tank in Washington,DC,And William Sahlman of the Harvard Business School believes that people will look back on this perido as a golden age of business management in the United States.
