水土保持是本世纪初才发展起来的一门新兴科学。我国在40年代初期,农业界的一些有识之士,将水土保持作为一门科学提出,并纳入了科学实验的轨道,建立了一些试验机构,开展了试验观测和示范推广工作。 1940年前后,原黄河水利委员会的林垦设计部门,在天水县的皂郊镇附近,建立了一个名为“陇南水土保持实验区”的径流观测场,进行不同土地利用条件下的水土流失观测,一二年后,原“农林部天水水土保持实验区”成立,便与之合并。
Soil and water conservation is a new science that developed at the beginning of this century. In the early 1940s in our country, some people of insight in the agricultural sector put soil and water conservation as a science and incorporated them into the track of scientific experiments. Some experimental agencies were set up and experimental observations and demonstration and popularization work were carried out. Around 1940, Linke Design Department of the former Yellow River Conservancy Commission established a runoff observing field called “Longnan Soil and Water Conservation Experimental Zone” in the vicinity of Zaojiao Town in Tianshui County to carry out soil and water loss observation under different land use conditions One or two years later, the former Ministry of Agriculture and Forestry Tianshui Soil and Water Conservation Experimental Zone was established and merged with it.
