Abstract

The invention discloses a miniature soil hydrologic monitoring system suitable for a high-heterogeneity karst sloping field. The miniature soil hydrologic monitoring system comprises a miniature region, a miniature interflow collecting system and a miniature direct surface runoff collecting tank. The miniature interflow collecting system is inserted below a sloping soil profile rock-soil interface below the sloping field miniature region for collecting interflow above the rock-soil interface; the miniature direct surface runoff collecting tank is inserted at the position of a sloping soil profile, which is close to the earth's surface for collecting direct surface runoff. The bottom surface of angle steel of the miniature direct surface runoff collecting tank is in contact with the top surfaces of an aluminum-plastic panel and a thin aluminum panel in the miniature interflow collecting system, and the miniature direct surface runoff collecting tank and the miniature sloping field region are fixed together through screws at two sides. According to the miniature soil hydrologic monitoring system, direct surface runoff and interflow of the miniature sloping field region can be simultaneously measured, the difficulty that the soil hydrologic process is monitored on the high-heterogeneity karst sloping field is solved, and a platform is provided for researches on aspects of the hydrologic process, the soil and nutrient loss principle, the karst process and the plant water adaptive mechanism in such karst sloping field.

Description

technical field

[0001] The invention belongs to the fields of ecology, hydrology, soil erosion and soil and water conservation, and more specifically relates to a miniature soil hydrology monitoring system suitable for highly heterogeneous karst slopes, suitable for teaching, scientific research and environmental protection departments to carry out slope hydrology under natural and artificial influences Systematic determination and study of processes, water and nutrient transport. Background technique

[0002] The soil-forming process in the karst area of ​​Southwest China is very slow, the water storage capacity of the shallow soil layer is weak, coupled with the abundant karst pores and fissure structures, a large amount of surface water seeps, the pollution of groundwater is becoming more and more serious, and droughts and floods are frequent. Water is the solution to ecological problems in karst areas. , the key to achieving sustainable socio-economic development. Recen...
