Description
Technical field
The present invention relates to a kind of Watershed Scale water erosion fine analog test method of systematic study Soil Erosion in Small Watershed process and mechanism, especially different landform shapes can be filled according to testing requirements, the soil of filling different-grain diameter composition, the soil weight of manual control basin Different geomorphological positions, lay Different geomorphological positions (domatic top, basin, lower slope, raceway groove) etc. soil and water conservation measure, control rainfall intensity and process, observation Different geomorphological positions current hydrodynamics characteristic, thus can different condition area be realized, soil erosion accurate analog in basin under different rainfall, under research different underlying surface, each factor is on the impact of soil water erosion process and Response Mechanism.
Background technology
Small watershed different geomorphologic units water erosion process alignment of basic pattern monitoring test method selects complete catchment area in the wild, set up domatic top, bottom, full the geomorphic unit runoff experimental plot such as domatic according to natural feature, set up discharge site at the exit or entrance of a clitch of Zhigou and tap drain and carry out dynamic monitoring.Select more consistent domatic of comparatively homogeneous, the gradient of soil property, the rectangle community measuring different length of grade, different gradient and different in width is needed according to test, the materials such as asbestos tile are used to be separated with surrounding is domatic by selected areas, slope runoff experimental plot is laid according to natural feature, in community, the selected vegetation of plantation or maintenance nature are coated to, lay catchment port, runoff pond and diversion box at the runoff plots end on domatic top, the runoff plots of lower slope and complete domatic community end lay catchment port, triangular groove.To comprise before the runoff yield of one rainfall event, sediment yield, rain soil moisture content after rain in slope runoff district observation, Zhigou and tap drain hydrometric station observation project have water level, discharge process, water cut process, sand grains gradation.Research sediment bypassing characteristic.
But, field land surface condition is comparatively complicated, the factor such as soil property, the gradient, mima type microrelief, ant cave, surface crust all watershed water erosion process and result can produce considerable influence, the quantitative effect of single Factors on Soil Erosion dynamic process is difficult to peel off, and greatly constrains the further investigation of soil erosion process and mechanism; For the domatic community of field prototype, only observation is to exit, runoff experimental plot runoff, sediment flow behavior total amount, lack the measurement of Slope-Runoff, Sediment Transport Process, lack the measurement to slope runoff Hydrodynamic Process, for raceway groove, only runoff, the Sediment Transport Process of observation basin Outlet Section, the Hydrodynamic Parameters for raceway groove different section is difficult to obtain, therefore, be difficult to disclose watershed sediment from the domatic water erosion dynamic process exported to basin; And prototype observation test need carry out under outdoor natural rainfall condition, be subject to the very big restriction of weather conditions, be difficult to the impact comprehensively studying the condition watershed soil erosion processes such as different rainfall amount, rainfall intensity, rainfall, rainfall pattern, and field condition is unfavorable for accurate measurement and the collection of test parameters.
In simulation laboratory test, at present, domestic and international soil erosion solid model belongs to small-sized domatic soil box mostly, shop experiment simulated object spininess to the domatic top in field, bottom and entirely domatic and the erosion caused by sloping surfaces runoff plots that is that build, and by also fewer for the Watershed Scale simulation test research of the erosion caused by sloping surfaces and groove channel erosion integrally process.Existing Watershed Scale simulation test only observes the husky process of the water of basin Zhigou, tap drain, but, Erosion and Sediment Production in Watershed is a complete Hydrology mechanical system be made up of the erosion Sediment Transport Process occurred on domatic, raceway groove, only carry out the modeling effort of the erosion caused by sloping surfaces, or using the erosion caused by sloping surfaces and groove channel erosion as two isolated processes in addition experimental study be all inadequate.Therefore, modeling effort is carried out to the water erosion process in the complete basin including domatic and raceway groove composition, just necessary.
