摘要

根据福建省长汀县径流小区2014-2018年的实测资料，对不同土地利用方式下的坡地侵蚀特征进行研究，分析各径流小区土壤流失量、径流量与降雨、水土保持措施、植被等因子的关系。结果表明：不同土地利用方式、不同水土保持措施的径流小区土壤流失量、径流量特征不同；年降雨量对各径流小区的年土壤流失量影响不显著，不同水土保持措施对径流小区的年土壤流失量影响显著；年降雨量和不同水土保持措施对各径流小区的年径流量影响均为显著；年土壤流失量和年径流量与年降雨量的相关系数均与水土保持措施及径流小区植物的种类和生长有关；各径流小区的年土壤流失量与年径流量均呈正相关，即年径流量越大，年土壤流失量越大。研究结果为长汀县水土流失治理提供参考。

Abstract

Base on the measured data from 2014 to 2018 on runoff plots in Changting County of Fujian Province

the slope erosion characteristics of various land uses were studied. How the loss of soil and runoff were influenced by rainfall

soil and water conservation measures and vegetation was analysed

and the results showed that characteristics of the loss of soil and runoff are different on runoff plots of various land uses and with various soil and water conservation measures. The effect of annual rainfall on the annual loss of soil of runoff plots was not significant

whereas the effect of various soil and water conservation measures significant. Both the effect of annual rainfall and various soil and water conservation measures on the annual runoff of runoff plots were significant. The correlation coefficients between the annual loss of soil and the annual rainfall

the annual runoff and the annual rainfall were both related to the soil and water conservation measures and the species and growth of the plants in the runoff plots. There was a positive correlation between the annual loss of soil and annual runoff

which means the annual loss of soil increases with the annual runoff. This study can serve as a reference for water and soil loss control in Changting County.
