我国西北5省(区)林业系统自然保护区的分布特征和类型结构分析

Analysis on Distribution and Type of Forest Nature Reserves in Northwest China

通过对陕西、甘肃、宁夏、青海、新疆西北5省(区)已建林业系统自然保护区的数量、面积、级别特征的论述及其类型结构的分析表明,此西北5省(区)自然保护区的平均数量尚未达到全国的平均水平,且各省区分布不均衡;保护区的类型比较齐全,国家重点保护的一、二级野生动植物在已建的自然保护内已得到了很好的保护。但自然保护区的布局有待进一步合理化;据此,提出了加强保护区的网络化建设,扩建已有的保护区,将具有重要意义的省级自然保护区升级为国家级自然保护区等建议。

The quantity, area and type of forest nature reserves established in Shann＇xi, Gansu, Ningxia, Qinghai and Xinjiang were analyzed. The analysis results showed that the quantity of forest nature reserves in these five provinces of northwest China did not reach the average level of the whole country, and the nature reserve distribution in these five provinces was not even. The types of nature reserves were basically complete, and the wildlife and plant belonging to national protective class Ⅰ and class Ⅱ were effectively protected. Still, it is necessary to rationalize the distribution of forest nature reserves of northwest China, to strengthen the network construction, to expand the establishment of nature reserves, to upgrade the important provincial nature reserves to national nature reserves.
