- Abstract:
- Through soil and water conservation monitoring on effects of check dams demonstration project, the dynamic changes of check dam and soil and water conservation measures on slope were analyzed. Water storage and silt detention effects and crop output effect associated with check dams were identified as well. The results showed that the amount of silt detention varied from year to year, firstly decreasing dramatically then increasing slightly because of the different precipitation characteristic and channels; the crop output on check dams was 36.4% higher than that on terrace, 78.9% higher than that on sloping land. In the end, a couple of principles about soil water conservation monitoring on dam system were outlined, which was meaningful to perfect construction and assessment of check dams in small watershed.
