GAP Analysis On The Biodiversity Conservation Of Jiuzhaigou Nature Reserve

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.
