摘要
为分析哈尼梯田湿地水文特征,更好地为保护利用哈尼梯田湿地水资源提供科学依据,通过野外调查计算和水样分析,得到了梯田蓄水和水质变化特征。结果显示:梯田蓄水量包括地表蓄水量和梯田下方土壤蓄水量,旱季地表蓄水量为169065.67m^3,雨季地表蓄水量可达372304.2m^3。0~60cm土壤蓄水量为451176.1t。水流经过森林—村寨—梯田,水质经历了好—差—好的变化。说明梯田湿地具有良好的蓄水效应和净化水质的作用。
In order to analyze the hydrological characteristics of Hani terrace wetland,this paper provides scientific basis for better protection and utilization of Hani terrace wetland water resources.Through field survey calculations and water sample analysis,the characteristics of terrace water storage and water quality change were obtained.Terraced field water storage includes surface water storage and soil water storage under terraces.In dry season,surface water storage is 169,065.67 m^3,and in rainy season,surface water storage can reach 372,304.2 m^3.The soil water storage from 0 to 60 cm is 451176.1 t.Water flows through forest-village-terrace,and water quality experienced good-bad-good change,which indicates that terrace wetland has a good effect of impounding and purifying water quality.
