Sustainable land use:literature review and research progress
摘要
The concept of Sustainable Land Use(SLU)was firstly proposed at the first interna-tional symposium on sustainable land use that was held by Indian Council of Agricuiltural Re-search ( ICAR ),United States Department of Agriculture ( USDA ) and United States Rodale In-stitute at New Delhi on1990.From then on ,extensive research works has been performed in-ternationally by many scholars and research societies ,covering all aspects that related to sus-tainable land use.This paper aims at reviewing literature on sustainable land use research ,ex-pounding research progress ,and lastly advising future research directions.Firstly ,concept and connotation on SUL was identified ,which can be expressed as land use structure and land use approach that can fulfill improving human demand ,reserve and improve human living stan-dard ,to be harmonious and effective on land use structure ,ecologically suitable ,economically viable and socially acceptable.Secondly ,research scope and objectives on SLU were also illus-trated.The fundamental objectives on SUL study is to investigate land use dynamics ,to forecast future changing directions ,as well as to analyze driving factors to these changes and lastly to select suitable decisions on sustainable land use strategy at different scales.So ,research focus-es on investigating land changing process ,and formulating regionally or globally integrated models.On international research progress ,three aspects on SUL study are summarized and dis-cussed ,which includes systematic analysis ,assessment and integrated research models on SUL.Following conclusions can be drawn through literature review and research progress investiga-tion:①SUL study must be performed under extensively international cooperation and multi-discipline scholars.②On modeling approach to mechanism and progress analysis on SUL ,multi-space and hyper-time models should be fulfilled based on scientific and perfect theory base.③SUL modeling approach should be performed on mecha
