平顶山市山丘区沟道治理与开发利用研究

Study of Gully Harness and Development and Utilization in Mountain Areas in Pingdingshan Prefecture.

平顶山市山丘区人均基本农田不足0.033hm^2,治理开发沟道水土资源是发展农业的重要出路.据对土石山区、黄土丘陵沟壑区典型沟道进行的治理开发研究,两区沟道治理开发程度分别达到93.0%、95.8%,坡面治理程度分别达到时94.5%、91.8%,则相应的沟道治理措施的年保土效率分别为29.3%、22.4%,年蓄水效率分别为8.4%、11.7%1995年全市山丘区沟道治理经济效益达4640万元 研究所提出的两种治理开发模式,在同类地区具有重要的推广应用价值.

Harness and development of water and soil resources in gullies are important ways for agriculture development in the mountain and hilly areas in Pingdingshan prefecture because there is only basic farmland of less than 0.033 km^(2) each person. Based on the study of harness and development of typical gullies in rolling hilly loess region and rocky mountain region, the development and harness degrees in gullies are respectively 93 % and 95.8 % for the two mentioned regions, and on slopes are respectively 94.5% and 91.8%, the annual soil conservation efficiencies are respectively 29.3% and 22.4% , and water storage efficiencies are 8.4% and 11.7%. The economic effect of the prefecture from the mountain and hilly regions harness in 1995 was 46 400 thousand RMB. The two harness and development patterns in the paper from study are of important value for application and extension in similar areas.
