Study On Plant Diversity Effects To Erdengyan Nature Reserve On Hydroelectricity Project

The hydroelectricity project is located at Laodukou, Mashui River, Enshi, HubeiProvince. In order to study its effects on the plant diversity of Erdengyan musk-deer andmacague nature reserve, this paper made a systemic research on the protection of plantdiversity among the 483m-high reservoir submerged area which were governed by thenature reserve, project processing area, lower reaches area of the main dam and thenature reserve above the 483m submerge d line. The result of the research indicates thatthe plant resource in Erdengyan musk-deer and macague nature reserve is abundant.There are 504 species, 309 genera and 121 families of vascular plants, including 22species, 19 genera and 14 families of Pteridophyta; 5species, 5 genera and 4 families ofGymnosperm; 477 species, 285 genera and 103 families of Angiosperm. Vegetationtypes primarily including bamboo forest, evergreen broad-leafed' forest, deciduousbroad-leafed forest, shrub-berry, evergreen coniferous forest, etc. studies on the analysisof influential factors of submerged area effects on the state key protecting plant and staterare tree species, projects processing stage effects on plants distribution and plantdiversity in the natural reserve, Which is especially taken as the provincial nature reservefor musk-deer and macague; and also on the proper analysis of effects of the Hydroelectricity projects on their food supply and inhabitation environment in the area. basedon the analysis and according to the actual circumstances of the investigation area, weapplied the basic principles of ecology and protection thesis and proposed five protectionstrategies and measures to lessen the effects of the Hydroelectricity projects on plantdiversity in Erdengyan nature reserve and therefore supplied a scientific method for themaintaining of bio-diversity and stability of eco-system in the area.At last, with the scientific developing view, we analyzed and discussed thedialectical relationship between the small or medium scaled Hydroelectricity project andthe plant diversity protection in local nature reserve, and therefore provided scientificevidence and basis on now to keep the harmonious development between ecology andeconomy when implementing small or medium scaled Hydroelectricity projects in themountainous area in our province in the future.
