塔里木河中游输水堤防外的地下水质变化分析

针对塔里木河中游输水堤防修建与生态保育的问题,结合对沙子河和阿其河两个断面地下水质的监测资料的分析,对输水堤防修建后堤防外地下水质的时空变化进行了探讨,揭示了在输水堤防影响下堤防外地下水质变化的初步规律.结果表明：沙子河断面和阿其河断面洪枯期地下水矿化度的变化规律由于堤防的修建而被改变,同样在堤防外侧,由于无地表水经过,沙子河断面地下水矿化度远高于在有生态闸定期放水的阿其河断面,因此,生态闸建设对抑制由于输水堤防影响而导致的水质修建具有积极作用.

Relationship Between Tourism Development and Vegetated Landscapes in Luya Mountain Nature Reserve, Shanxi, China

The relationship between tourism development and vegetated landscapes is analyzed for the Luya Mountain Nature Reserve (LMNR), Shanxi, China, in this study. Indices such as Sensitive Level (SL), Landscape Importance Value (LIV), information index of biodiversity (H’), Shade-tolerant Species Proportion (SSP), and Tourism Influencing Index (TII) are used to characterize vegetated landscapes, the impact of tourism, and their relationship. Their relationship is studied by Two-Way Indicator Species Analysis (TWINSPAN) and Detrended Correspondence Analysis (DCA). TWINSPAN gives correct and rapid partition to the classification, and DCA ordination shows the changing tendency of all vegetation types based on tourism development. These results reflect the ecological relationship between tourism development and vegetated landscapes. In Luya Mountain Nature Reserve, most plant communities are in good or medium condition, which shows that these vegetated landscapes can support more tourism. However, the occurrence of the bad condition shows that there is a severe contradiction between tourism development and vegetated landscapes.
