甘肃省地处西北黄土高原,常年气温干燥,雨量较少,地下水位低,推广地下库储粮具有优越的条件。我省地下粮库始建于陇东山区,随后发展到兰州、河西等地。据八五年普查统计,我省有各种地下仓库若干座(包括喇叭仓、砖园仓、石洞仓、窑洞仓等),总容量若干万吨,在粮食储藏中发挥了重要作用。实践证明,地下粮库明显的优点有四:一是占用耕地少,耗用三大材料少,投资费用少。初步计算,地下库平均每二千五百吨占地二至三亩,较同容量地面库占地五亩减少百分之六十;耗用三大建筑材料为地面库的百分之十左右;每百吨造价为地面库的百
Gansu Province is located in the northwestern Loess Plateau, with annual dry temperatures, less rainfall, low groundwater table, and favorable conditions for popularizing underground storage and grain storage. The underground grain depot in our province was built in Longdong mountainous area, then developed to Lanzhou, Hexi and other places. According to the 1985 census, there are various underground warehouses in the province (including trumpet warehouses, brick warehouses, stone cave warehouses, cave warehouses, etc.) with a total capacity of some 10,000 tons and have played an important role in grain storage. Practice has proved that there are four distinct advantages of underground grain storage: First, less land occupation, less consumption of three major materials, less investment costs. According to a preliminary calculation, the underground warehouses occupy an average of 2 to 3 mu for every 2,500 tons, a decrease of 60% over the five mu for the same floor lot. The three major building materials consumes about 10% of the surface area ; Per hundred tons for the ground floor of the reservoir hundred
