By means of the statistical analysis of the experimental data measured on 32 experimental spots over three years continuously, the soil loss equation of cultivated slopeland in northeast mountain region of Yunnan province has been developed as follows: A=R·K·LS·C·P.
该项研究通过对32个试验小区连续3a实测数据的统计分析,建立了滇东北山区坡耕地土壤流失方程A=RKLSCP;并确定了方程中诸因子的求算方法和数值,以及滇东北山区土壤允许流失量,为方程的应用提供了基本的技术数据。
By means of setting up experimental spots of the controlling effect of five main soil conservation measures (i.
通过对滇东北山区坡耕地5种主要水土保持措施———等高带状耕作、地埂、生物防冲带-绿肥、生物防冲带-苹果、水平梯地(梯田)对土壤流失量的控制作用建立试验小区并进行连续3年实测,得到各种水土保持措施的P值,为建立坡耕地水土流失方程、进行土壤侵蚀预测预报、制定坡耕地水土保持措施奠定了可靠的基础。
By means of setting up 18 experimental spots and measuring continuously over three years on different slope and length of sloping cultivated land in the northeast mountain region of Yunnan province,the equation of the topographic factor (LS) in this region is defined as: LS=L20 0 24 S5° 1 32 , in it, L is length of slopeland (m), S is slope (°).
通过在滇东北山区坡耕地上设置18个不同坡度和坡长的试验小区,并进行连续3年实测,得到本区域土壤侵蚀地形因子(LS)的定量关系式,据此求得滇东北山区坡耕地土壤侵蚀的坡面地形效应(LS值)表。
Ten experimental plots different in land use were set up to study characteristics of soil erosion and nutrient loss under natural precipitation in Zhangjiachong Watershed.
为研究三峡库区土地耕作措施对土壤侵蚀和营养物质流失的影响,在三峡库区张家冲小流域设置10个不同土地利用方式的试验小区,在自然降雨条件下,进行为期1 a的小区试验,研究不同土地利用方式下土壤侵蚀和径流中氮、磷流失特征。
