摘　　要：总结了贵州花江喀斯特峡谷石漠化生态治理示范区地下水的发育特征和含水介质的差异,同时选择贞丰县北盘江镇马刨井和关岭县板贵乡万年坟火龙果基地两地地下水和雨水蓄水池的水质进行了检测。结果显示,以裂隙地下水为水源的马刨井水池各项检测指标均达到国家饮用水标准要求,而以雨水为水源的万年坟火龙果基地水池在悬浮颗粒物、p H、耗氧量等指标达不到饮用水标准。藻类的生长导致p H随光照变化而变化,正午时达到最大。而夜晚由于呼吸作用使得耗氧量增大,藻类的生长使得雨水蓄水的水质达不到饮用水标准,仅适用于农业灌溉。由此,提出改进措施保证蓄水水质。The characteristics of groundwater in the zone of Huajiang Canyon Karst rocky dcsertification and differences of water containing medi- um were summarized. At the same time selecting Mapaojing in Beipanjiang Town, Zhenfeng County and Wannianfen in Bangui Town of Guanling County as testing field, the quality of groundwater ands torage pool water were tested. The results demonstrated that groundwater in cracks and fissures of Mapaojing satisfied the national standard of drinking water, while the suspended partickes, oxygen consumption and other aspects in water rain pool of Warmianfen are not up to the national standard of drinking water. It was found that algae growth caused pH and oxygen con- sumption change by illumination altering. That is to say pH will reach the peak at noon and oxygen consumption will increase at night for the res- piration. Growth of algae make quality of rainfall not up to drinking, which can only suit for agricultural irrigation. At last ,measures to ameliorate water quality were put forward.
