【摘要】 本文以九寨沟自然保护区为研究实体,借助地理信息系统软件Arcinfo9.0和遥感技术,采用GAP (a Geographic Approach to Protect Biological Diversity)分析方法,在定性描述研究区物种多样性、生态系统多样性特征的基础上,以九寨沟自然保护区生物多样性的保护现状为研究对象,结合人类干扰分布及现有保护网络,对珍稀植物、重点保护鸟类、珍稀兽类、两栖爬行动物四类物种分别进行保护空缺分析,找出未受到保护的物种和区域,即"gaps",分析出现"gaps"的原因,并有针对性地从资源保护、资源管理及游客管理三个方面提出了保护建议。主要研究结果如下:1、不同功能区域内受到的干扰源存在差异性,核心区以偷猎、放牧和挖药为主,缓冲区以放牧为主,试验区以旅游为主。2、植被类型由12类构成,主要群落为冷杉林、云杉林的亚高山常绿针叶林面积最大,约占全区总面积的39.95%。3、人类活动是影响动物物种分布及产生保护空缺的主要原因,其中旅游活动的干扰尤为突出。四类被研究的物种中,珍稀植物、重点保护鸟类、珍稀兽类的主要分布范围均以核心区为主,适合后两者生存的海子等生境受到强度较高的旅游活动影响是此分布特征的直接原因,而对原生生境依赖性大、对环境变化十分敏感的两栖爬行动物主要分布区仍位于试验区,但数量在急剧下降中。4、以现有的保护站管护范围为依据,划分出7个保护空白片区,其中红豆杉、银杏、独叶草、红花绿绒蒿、领春木、红椿、水獭、牛羚、斑羚、绿尾虹雉、藏雪鸡、蓝马鸡、血雉、斑尾雉鸡、雉鹑等物种是特别需要立即采取保护措施的重点保护物种。

【Abstract】 This thesis takes the Jiuzhaigou Nature Reserve as object of study. With the assistance of GIS software Arcinfo 9.0, the research adopts GAP analytic method. Based on the identification of biodiversity features of the studied area, the research combines the circumstances of human intervention and the existing conservation network, conducts GAP analysis on the protected situation of rare plants, the key protection avifauna, rare animal, amphibian and reptile, finding out unprotected species and the locations of their habitats, namely gaps, and the reasons for the existence of such gaps. And protection measures can be put forward from three aspects, such as resource protection, resource management and visitor management.The major results of this research are the follows:The interference source is difference in the three functional areas. The main interference source include poach, herd, medical herb gathering in the core zone, herd in the buffer area, and tourism in the experimental area.The vegetation is constituted by twelve types, and the area of subalpine evergreen coniferous forest is the largest, which is made up of the the fir forest and spruce forest mainly, accounting for 39.95% in the total area of the region.Human activities are the main reasons for impacting distribution of animal species and producing the protection gap, especially tourist activity. In four studied species, rare plant, avifauna, rare animal are located at core zone manily. The immediate cause is that the habitat for the avifauna and rare animal is effected by the high intensity of tourism activities, such as "haizi". Amphibian and reptile are still located at experimental area,which are dependent on the original habitats and sensitive to environmental change very much, however the number is diminishing sharply.Takes the management scope of the present protection stations as the basis, we can divided the protection gaps into seven areas. The key protected species which need to be taken measures to immediately, are Chinese Yew (Taxus chinensis (Pilger) Rehd.), Ginkgo (Ginkgo biloba L.), Root or leaf of dockleaf goldenray (Kingdonia uniflora Balf. F. et W. W. Smith), Redflower meconopsis inflorescence and fruit (Meconopsis punicea Maxim.), Franchet Euptelea (Euptelea pleiospermum Hookf. et Thorns.),Toon (Toona ciliata), Otter (Lutra lutra), Gnu (Budorcas taxicolor), Common goral (Naemorhedus goral), Chinese monal pheasant(Lophophorus lhuysii), Tibetan Snowcock Tetraogallus tibetanus (Tetraogallus tibetanus), Blue Eared Pheasant (Crossoptilon auritum), Blood pheasant (Ithaginis cruentus), Mrs.Hume’s Pheasant (Syrmaticus humiae), Pheasant grouse (Tetraophasis obscurus)and so on.
