A Study of Scientific Regulation of Sustainable Land Use at County Scale in China

It is necessary to evaluate sustainable land use control at county scale in China. The scientific control system of sustainable land use is deeply studied from three aspects: land use zoning, sustainable land use assessment and sustainable land use monitor. Restricting irrational land use and avoiding the negative effect of land use are social targets of the system of land use zoning. The beforehand regulating way is the available public measure land management. The system of sustainable land use assessment is to evaluate sustainable land use at county scale. In a feedback way, irrational land use will be avoided. Sustainable land use indicators at the county scale are built up based on the character of sustainable land use indicators and the trait of land resources in a county. The system of sustainable land use monitoring is timely to monitor land use/land cover changes and environmental changes. In a timely way, irrational land use will be avoided. The controlling object of regulation system of sustainable land use is land use system at county scale, and the final aim of this system is to ensure sustainable land use at county scale. Some valuable and useful information can be got for the rational land use through this system. And based on the system, some sustainable land use policies are also offered.
