Metamodelling phosphorus best management practices for policy use: a frontier approach
用前沿分析法为明尼苏达州东南部流域的农田建立磷减排成本函数元模型，评估减少非点源磷排放的政策，发现高效政策使磷排放减少40%的成本为每农场844美元。
Abstract This article presents a modelling system for synthesising heterogeneous productivity and nutrient loading potentials inherent in agricultural cropland for policy use. Phosphorus abatement cost functions for cropland farmers in a southeastern Minnesota watershed are metamodelled using frontier analysis. These functions are used to evaluate policies aimed at reducing nonpoint phosphorus discharges into the Minnesota River. Results indicate an efficiently targeted policy to reduce phosphorus discharge by 40% would cost US$167,700 or 844 per farm.
