Basing Superfund Cleanups on Future Land Uses: Promising Remedy or Dubious Nostrum?
Abstract: Supporters of the effort to link cleanups at hazardous waste sites to the sites' expected land uses claim that amending language in the federal Superfund statute to allow this may yield a number of benefits. These include rationalizing the cleanup process and decreasing cleanup costs, promoting economic development in the local communities that host Superfund sites, and helping such communities exercise more control over the cleanups. However, interviews with Superfund stakeholders and a detailed case study call into question these arguments. The current role of land use in cleanup, uncertainties about whether economic development is likely at the bulk of Superfund sites, the long-run viability of institutional controls, the willingness of communities to accept cleanups that leave contamination on-site, and the nature of public involvement all suggest-that the benefits of tying land use to remedy selection may not be so straightforward.
In the past 19 years,while China's urbanization was fast-developing,a series of problems related to urbanization were there upon production.In this paper,based on spectrum characteristic of knowledge method,the thematic information of three periods of LUCC were extracted from Landsat TM,ETM + and CBERS-2.Combing with the GIS technology,the land-use transfer matrix from 1987 to 2006 were obtained.Besides,the LUCC models were applied to analyze the characteristic of land use change from 1987 to 2006.Based on the land-use change map and land-use transfer matrix,spatial dynamic characteristic and land-use conversion of the study area were analyzed.The research could provide suggestions for land management and making policy for local government.
