Investigation and Water quality Analysis of Agricultural nonpoint Source pollution in Tanxia Town
نویسندگان
چکیده
Taking the small watershed in Tanxia town as an example, classified investigation of agricultural non-point source pollution tributaries Lijiang River was carried out, sources local were analyzed, and surface water environmental quality standard Nemero index method used to evaluate basin. The results show that basin is poor exceeds all year round, mainly depends on chemical fertilizer. Improving use fertilizer rational application are key factors improve pollution.

Multiple Agents, and Agricultural Nonpoint-Source Water Pollution Control Policies
Assuming asymmetric information over farmer profits and zero transaction costs, prior literature has suggested that when regulating nonpoint source water pollution, a tax on management practices (inputs) can implement full-information allocations and is superior to a tax on estimated runoff. Using mechanism design theory under asymmetric information, this paper shows that under the same assumpt...
متن کاملAgroforestry buffers for nonpoint source pollution reductions from agricultural watersheds.
Despite increased attention and demand for the adoption of agroforestry practices throughout the world, rigorous long-term scientific studies confirming environmental benefits from the use of agroforestry practices are limited. The objective was to examine nonpoint-source pollution (NPSP) reduction as influenced by agroforestry buffers in watersheds under grazing and row crop management. The gr...
متن کاملReducing Nonpoint Source Pollution
76 Vegetated buff ers are a well-studied and widely used agricultural management practice for reducing nonpointsource pollution. A wealth of literature provides experimental data on their mitigation effi cacy. Th is paper aggregated many of these results and performed a meta-analysis to quantify the relationships between pollutant removal effi cacy and buff er width, buff er slope, soil type, a...
متن کاملNonpoint Source Pollution
A Total Maximum Daily Load (TMDL) program has been initiated in the North Bosque River Watershed in Texas, USA, where point and nonpoint sources of pollution are of a concern. The Soil and Water Assessment Tool (SWAT), which had been validated for flow and sediment and nutrient transport, was applied to quantify the effects of Best Management Practices (BMPs) related to dairy manure management ...
متن کاملIncluding Source-Specific Phosphorus Mobility in a Nonpoint Source Pollution Model for Agricultural Watersheds
Most widely used nonpoint source models associate pollutant loads almost exclusively with land use via pollutant export coefficients and some kind of runoff coefficient. Not surprisingly, the range of management options suggested by such models’ simulations are largely linked to changes in land use. This problem is addressed by developing models of dissolved phosphorus DP mobility for specific ...
