Abstract：Soil and water losses of development and construction projects,the result of integrative influence of complicated natural condition and human activities,is a typical erosion phenomena caused by human advanced which is gusty,intense and harmful.The mechanism of soil and water losses of development and construction projects is more complicated which brings difficulty to the soil and water conservation monitoring.Monitoring points arrangement is the most important basic work of soil and water conservation monitoring.Its rationality determines the objectivity of monitoring result including soil and water losses dynamics,soil and water conservation facilities implement and its effect.At present,there is no uniform criterion of monitoring arrangement which has brought uncertainty to the monitoring design work.This paper puts forward a points arrangement pattern of soil and water conservation monitoring of development and construction projects based on the theory of stratified sampling.It takes erosion type,terrain type,land-use type and function units as main control factors and adopts a four-grades controlling sub-area.The method of monitoring points arrangement can transform complicated work into relative simple work when constructing a gradual detail monitoring form whole project section into fixed points.It can help resolving the problem of the monitoring difference caused by natural condition and project characteristics.
