新疆阿勒泰林场林地保护与利用研究

新疆阿勒泰林场林地保护与利用存在着地域性分布明显,树种单一,稳定性差,林牧矛盾突出、林地管理缺乏规范等问题。提出实行用途管理,进行森林保有量规划,根据生态脆弱性、生态区位重要性以及林地生产力等指标对林地资源进行系统评价和定级结果:特殊保护(Ⅰ级保护)面积占林地面积的41.2%、严格保护(Ⅱ级保护)面积占27.3%、重点保护(Ⅲ级保护)面积占31.5%、一般保护面积(Ⅳ级保护)为零。根据以往各类规划中的定位,将林场划分为"禁止开发区"和"限制开发区"2个生态功能区。

Study on Protection and Utilization of Forestland at Aletai Forest Farm in Xinjiang

There are problems existed in forestland protection and utilization in Aletai forest farm of Xin-jiang like distinct regional distribution, limited tree species, poor stability, obvious contradiction be-tween forestry and animal husbandry, as well as lack of forest management specification. It was proposed to implement purpose management, conduct forest inventory planning, and carry out woodland resources system evaluation and grading in accordance with ecological fragility, importance of ecological zone bit and forest productivity and other indicators. The results show that ： special protection （ class Ⅰ protection） area accounted for 41.2% of the woodland area, strict protection （level Ⅱ protection） area accounted for 27.3% , key protection （Ⅲ level protection） area accounted for 31.5% , and general protection area （ level Ⅳ protection） was zero. According to the definition in the past planning, the forest is divided into two ecological function areas of ＂prohibited zone＂ and ＂restricted zone＂.
