我们曲峪大队,有736户,2,607口人,历史上是个“十年九不收”的穷地方,全村1.9万亩总面积中就有1.5万亩植被稀少、水土流失十分严重的土地。山地面积占总面积74.5%,海拔790—900米,无霜期150天左右,平均气温9.5℃,1月最低零下26.4℃,7月最高可达36.6℃,年降雨量480毫米左右。有大小山头20个,干沟12条,沟壑密度每平方公里1.51公里。基岩为二垒三垒纯紫色页岩,夹有砂岩。据中国科学院黄河中游水土保持考察队1955年调查,每平方公里年侵蚀量有13,900吨肥土流入黄河。因而过去粮食产量极低,亩产不过百斤,总产正常年景也不过六、七十万斤。
We Quyu brigade, there are 736 households, 2,607 people, history is a “ten years nine do not accept” the poorest places, the total area of 19000 acres of the village there are 15000 acres of rare vegetation, soil erosion is very serious land. The mountainous area accounts for 74.5% of the total area, with an altitude of 790-900 meters, an average frost-free period of 150 days, an average temperature of 9.5 degrees Celsius, a minimum of 26.4 degrees Celsius in January and a maximum of 36.6 degrees Celsius in July with an annual rainfall of about 480 mm. There are 20 hills, dry ditch 12, gully density 1.51 kilometers per square kilometer. Base rock third base third pure purple shale, sandstone sandwiched. According to a survey conducted by the Chinese Academy of Sciences in the Yellow River Mid-stream Soil and Water Conservation Expedition Team in 1955, there were 13,900 tons of soil erosion per square kilometer flowing into the Yellow River. In the past, therefore, the output of grain was extremely low, but the per-mu yield was only one hundred pounds. The total annual output of normal production was no more than six or seven hundred thousand jin.
