- 摘要:
- 研究了农业旅游开发对呼伦贝尔沙质土壤草甸草原植被—土壤等生态环境的影响。结果显示：1）农业旅游开发显著降低了植被覆盖度、丰富度指数、均匀度指数和多样性指数（p < 0.05），对植被优势度指数没有显著影响（p > 0.05）；2）农业旅游开发增加了土壤容重和pH，降低了土壤含水量和电导率；3）农业旅游开发显著增加了土壤粗沙（p < 0.05），显著降低了土壤粘粉粒（p < 0.05），对细沙和极细沙没有显著影响（p > 0.05）；4）农业旅游开发显著降低了土壤氮素（全氮和碱解氮）和钾素（全钾和有效钾）（p < 0.05），而土壤磷素（全磷和有效磷）则不受农业旅游开发的影响（p > 0.05），其中土壤钾素（全钾和有效钾）变化幅度较大，对农业旅游开发表现较为敏感；5）相关性分析表明：农业旅游开发下植被属性主要取决于土壤有效养分。
- Abstract:
- The effect of agriculture tourism development(ATD) on eco-environment of Hulunbuir was investigated. The results showed that: 1) ATD significantly reduced the vegetation coverage, richness index, evenness index and diversity index (p < 0.05), but had no significant influence on the dominance index (p > 0.05); 2) ATD increased soil bulk density and pH, reduced soil water content and electrical conductivity; 3) ATD significantly increased coarse sand of soil (p < 0.05), reduced the silt and clay in soil (p < 0.05), but had no significant influence on the fine sand in soil (p > 0.05); 4) ATD significantly reduced soil nitrogen (total nitrogen and alkaline hydrolysis nitrogen) and soil potassium (total potassium and available potassium) (p < 0.05), but had no significant influence on soil phosphorus (total phosphorus and available phosphorus) (p > 0.05), however, soil potassium (total potassium and effective potassium) was more sensitive to the ATD because of its large change range; 5) correlation analysis showed that vegetation properties mainly depended on the soil available nutrients in Hulunbuir prairie.
