GAO Zhaoliang, YANG Shiwei. Existing Problems of Silt Arresters on the Loess Plateau[J]. Bulletin of Soiland Water Conservation, 1999, 18(6): 16-19.DOI:
There are 100 000 silt arresters(SA) and 381 300 hm2 farmlands on the loess plateau that have been built since 1949. The widespread investigation showed that these SA have high effect of economic and social benefit on the soil and water conservation there. However
there were many problems in the SA construction and utilization
it especially showed at five aspects as follows: (1) The distribution of SA system are almost irrational and more weak and dangerous building. (2) Because of the low designing standard
the engineerings are easy to be destroyed and broken down. (3) The quality in specific implement of these structures is worse
and the engineering is not harmonious. (4) The bad management of structure bodies
loose mainte-nance. (5) The low utilization ratio and economical benefit of the filled farmlands.
