一、薪炭林类型区的划分原则和依据树种的生物学特性与立地条件的统一,是确保林木成活和良好生长的关键性环节,是实现林木速生丰产的前提。因此,因地制宜,适地适树是划分薪炭林类型的原则。而农村能源的余缺程度,社会经济条件,不同地区的林业发展方向是划分薪炭林类型区的重要依据。在 First, the principle and basis for the division of firewood forest type area The biological characteristics of tree species and site conditions are the key links to ensure the survival and good growth of forest trees. Therefore, according to local conditions, the appropriate tree is the principle of dividing the type of firewood forest. However, the degree of rural energy shortage, socio-economic conditions, and the direction of forestry development in different regions are the important bases for dividing the area of ​​fuelwood forest types. in
