英文文献摘要：
The invasive aquatic plants Hydrilla verticillata (hydrilla), Eichhornia crassipes (water hyacinth), and Pistia stratiotes (water lettuce) have the potential to negatively impact recreational use of Florida lakes if consistent, adequate control expenditures are not made. In the mid-1990's, Florida significantly reduced its spending on invasive aquatic plant control measures, which resulted in a significant increase in needed control expenditures in subsequent years. This paper attempts to formalize a relationship between coverage of these invasive aquatic plants and angler effort on Florida lakes using data on 38 lakes over 20 years. Estimated regression coefficients are used to simulate control alternatives, and expenditure cost-benefit comparisons are made.
入侵水生植物水螅(Hydrilla verticillata, Hydrilla)、水葫芦(Eichhornia crassipes，水葫芦)和层状雌蕊(water莴笋)可能会对佛罗里达湖泊的休闲利用产生负面影响，如果没有持续的、足够的控制支出的话。在20世纪90年代中期，佛罗里达州显著减少了在入侵水生植物控制措施上的支出，这导致了随后几年所需控制支出的显著增加。本文试图通过对佛罗里达38个湖泊20年来的数据分析，将这些入侵性水生植物的覆盖范围与垂钓者的努力之间的关系形式化。估计回归系数用于模拟控制方案，并进行支出成本效益比较。
