What are the factors that play an infulancing role in classifying forest ?
Answers
Answer:
uneven distribution of rain water in the forest
Answer:
Understanding the effects of site conditions and climatic factors on forest growth is important for the development of forest cover and forest management (Worrell and Malcolm, 1990a, b). Given the rapid rise of temperature (Houghton et al., 2001) and the possible average increase in precipitation of about 3.4 per cent globally per 1°C temperature rise that we face (Allen and Ingram, 2002), it is critical that we take climatic factors into consideration in the assessment of forest growth and prediction (Bonan et al., 1990; Tyler et al., 1995; Raich et al., 1997), especially in areas where climatic change is likely to reduce forest growth and cover.
The Taihang Mountains run from south-west to north-east in northern China (34° 35′–40° 19′ N, 110° 15′–116° 27′ E; Figure 1), and cover a region of 108 000 km2 (Yang et al., 1993), including part of Beijing City and Shanxi, Hebei and Henan Provinces. To the east of the Taihang Mountains, lie Beijing and one of China's largest agricultural production areas, the North China Plain (NCP). Improvement of the environmental conditions in the Taihang Mountains will be beneficial both to the environment of Beijing and to the water resources of the NCP downstream. Since 1950, intensive afforestation has been carried out in the region. Recently, the Taihang Mountains were selected as one of the five major afforestation regions by the Chinese central government. According to the scheme of the China State Department (1997), which runs to the year 2050, 35 600 km2 of forest is to be planted in the region, increasing the regional forest cover by >30 per cent.
