摘要
本文对黑龙江省土壤水资源和土壤水库进行研究。结果表明,我省土壤水资源非常丰富,全省约有900多亿立方水,是地下水资源的4～4.5倍。不同土壤类型土壤水资源有很大差异:黑土、草甸土等土壤水资源较丰富,每亩为180～200立方;风砂土土壤水资源最少。每亩为40～60立方;其它土壤为每亩160～170立方.土壤水资源存在土壤水库内,土壤水库类型可分为散水型土壤水库、贮水型土壤水库、隔水型土壤水库和渍水型土壤水库.
The research made during 1980～1986 shows that soil water resources in Heilongjiang
Province are very abundant,about 90 billion m^3 and 4～4.5 times as rich as those of under-
ground water.Water resources are different among soil types.Black soil and meadow soil
have higher moisture content,with 180～200m^3 per mu,sandy soil has the lowest water con-
tent,with about 40～60m^3 permu,and the other soil types have about 160～170 m^3 permu.
Soil water resources are stored in the soil water reservoirs.There are 4 types of them:
water-diffusing reservoir,water-storing reservoir,water-saparating reseryoir and
water-logged reservoir.
