"新三峡"旅游业提档升级研究

“新三峡”旅游资源丰富,但开发力度不够,没有完全发挥资源优势。旅游业没有成为支柱产业,不足以带动库区经济发展。因此,加快发展旅游业意义重大。分析了“新三峡”旅游业提挡升级的意义,提出了旅游业提档升级的原则和途径。     

Legal study on water environmental protection of Three Gorges Reservoir Area

Water environment security of the Three Gorges Reservoir Area has become a more extensive concern since the impoundment of the reservoir. This paper describes the existing water environmental hazards and defects in current legal system for water environmental protection in this area, and also discusses their possible causes and potential problems in the future based on first hand materials and other literature. According to the theories of integrated river basin management and environmental equity principle, legal proposals are put forward, which include building an unitary legal system dedicated to the Reservoir Area, setting up a basin authority of the Yangtze River to preside over the resources protection and development, using interests' compensation system to solve interest conflicts among different reaches, and making concrete regulations to direct public participation in water environmental security protection of the Three Gorges Reservoir Area.     

长春市石头口门水库CDOM的光学特性

2008年6月13日和9月23日2次对石头口门水库进行光谱测量,并测定有色溶解有机物(CDOM)、总颗粒物质量浓度、叶绿素a质量浓度等水质参数,分析石头口门水库CDOM的光学特性以及季节变化特征,同时讨论不同季节CDOM吸收在水体各组分总吸收中所占的比重.6月份CDOM主要来源为路源,而9月份CDOM主要由浮游植物的光学降解形成;光谱斜率S与a_CDOM(355)具有稳定的对数递减关系;石头口门水库总体上是非颗粒物吸收和CDOM吸收占据主导地位,叶绿素a吸收比率最小.

湖北三峡库区药用种子植物区系的研究

对湖北三峡库区的药用种子植物区系进行了统计分析,将783属归为四大类15个分布类型.区系成分以温带性成分(424属),特别是北温带成分(154属)为主体;热带性成分(266属),特别是泛热带成分(117属)所占的比例也很高,表明该地区为我国南北植物的交汇区域;中国特有分布多(31属)。

Benefit evaluation of the Three-Gorges Reservoir migration by an assessment index model based on analytic hierarchy process

An assessment index model was established to evaulate the benefit of the Three-Gorges Reservoir migration through the analytical hierarchy process. Totally 43 indicators were selected to assess the impact of migration on the economic, social and ecological environmental aspects of the migration communities, with the data of the indicators of the years 1992, 1998, 2002 which represented the period of premigration, the end of the first phase migration and the end of the second phase migration, respectively. The evaluation matrix is sufficiently consistent, with a consistency ratio CR equal to 0.086 3. The assessment turned out a benefit value for the economic subsystem in the year 2004 larger than triple the value in the year 1992, indicating a remarkable economic growth in the Reservoir area. The constantly increasing value for the social subsystem reflects the stable social situations. There is a slight decline in the assessment outcome of the ecological subsystem for the year 1998, which implies enviromental conservation was given insufficient importance during that period. On the whole, the implementation of the migration project is favorable to the Reservoir region, as confirmed by the stably increasing overall evaluation value from 42.22% in 1992 to 68.81% in 2002. However, there is still much room to improve from the status quo to the target criteria.     

三峡库区紫色岩小流域土壤侵蚀强度动态监测

研究以草堂溪小流域1990年、2000年、2004年和2007年四期TM和CBERS影像为数据源,利用ArcGIS9.3软件,通过图层叠加、统计分析等,提取草堂溪小流域不同类型土壤侵蚀与高程、坡度、土地利用等相应数据,计算出土壤侵蚀综合指数。结果表明：五种侵蚀类型在研究期内相互转化,轻度侵蚀面积增加最多,达2.61km2,集中分布在草堂溪北部、西北部和东南部;研究区土壤侵蚀强度1990年-2000年明显增加,2000年-2007年逐渐下降,但高于1990年。土壤侵蚀变化的影响因素有自然因素和人文因素。高程和坡度对土壤侵蚀的影响并不是单一的正相关,在高程0～500m,坡度0～25°范围内土壤侵蚀强度变化随高程、坡度的增加而增加,一旦超过这个范围,侵蚀逐渐减少;旱地仍然是土壤侵蚀变化的主要影响因素,尤其是1990年,2004年土壤侵蚀综合指数最高,分别为10.365,7.348。移民、政策支持也影响着土壤侵蚀的变化。针对相对难于控制的自然因素,应根据各因素不同等级的侵蚀情况合理布局配置植被和土地利用类型;人为因素,则主要通过调整土地利用类型,制定合理的移民规划和政策支持,减少土壤侵蚀。
