摘要
从研究江苏省林业发展现状入手,在分析2001~2010年造林面积情况和森林资源二类调查的基础上,认为江苏省森林资源中人造林比重过大、品种单一以及由此所导致的森林的生态作用未得以有效实现。在对江苏省2001~2010年农林牧渔业各项产值的研究后发现,江苏省林业产值在总产值中所占的比例很小,经济效益不明显。在对农林复合经营生态原理研究的基础上,从江苏省地形条件、自然资源、主要林产品、森林资源等实际情况出发,介绍了几种对江苏省林业经济的发展和生态环境的保护都具有现实意义的农林复合经营模式。
Starting from forestry development status of Jiangsu Province,on the basis of analyzing forestation area and forest resource secondary investigation during 2001-2010,it was pointed out that the eco-efficiency of the forestry is not fulfilled which can be attribute to the large proportion of artificial plantation and the loss of diversity.The study on the gross value of agricultural output of Jiangsu Province from 2001 to 2010 shows the proportion of the value of forestry is very small.The economic benefits of the forestry are not significant.On the basis of agroforestry ecological principle research,starting from actual situation of topography,natural resources,main forest products,forest resources in Jiangsu Province,several agroforestry modes which have practical significances to the development of forestry and the protection of eco-environment were introduced.
