Since the environmental ecological equilibrium has been destroyed, it is inevitable to value the environment. This article introduces comprehensively the environmental appraisal of the forest soil in Nancha of Heilongjiang Province. It also discusses a series of questions deaing with characteristics of the forest soil environment, the distribution of sample taking, soil sample analysis, the choice making of evaluation standards, the evaluation model, the relations between soil grades and so on.The study also makes a successful evaluation about the polluted levels of copper, zinc, lead, cadmium, chromium, mercury,arsenic and the toxic metals in soil, whose results are satisfied.We have taken the way by which grid distribing was combined with snake-shape distribing. After the soil sample was processed, we take measures in all cases with atomic absorption spectrophotometer and give the lowest detecting limit of each element.While calculating of the comprehensive index, Nemeioul Index is used, which pays more attention to the effect of the heavily polluted pollutants. Since there is no unanimous standard to set an evaluating standard, it is easy and practical to measure the metal content in the contrasted soil and precise degree of pollution can be obtained.

林区环境生态平衡遭到破坏,环境的质量评价势待必行。本文全面介绍了黑龙江省南岔林区土壤环境评价。针对环境的特点,对采样点的分布,采样方法,土样分析,评价标准的选择,评价模式的应用及土壤等级的划分等一系列问题进行了探索。力图使环境评价这一基础性工作尽快程序化,模式化和标准化。对土壤中铜、锌、铅、镉、铬、汞、砷等几种有毒金属污染物进行了评价,获得了满意的结果。 采用了网格法和蛇形法相结合的布点方法土样经予处理后,用原子吸收分光光度计测定并给出了各元素的最低检出限。评价方法采用污染指数这一数学模式。综合指数的计算采用内莫罗综合指数法,突出考虑了污染较重的污染物的作用。关于评价标准的确定,在目前尚无统一标准的情况下,选择土壤对照点中金属元素的含量作为评价标准,简单易行,结果也能较好的反应污染程度。

Having analysed the data of soil survey, the soil types have close relation to natural conditions and change with the external conditions. Soil distribution rule and change tendency were used to supply scientific basis for reasonably improving and utilizing soil. Dark brown forest soil in Taoshan are 5 subgroups, 9 soil geneus and 16 soil species in total; there are 4 soil types and 9 subgroups of azonal soil.

本文对桃山林区土壤普查进行分析,土壤类型与自然条件密切相关,而且随着外界条件变化而逐渐变化。掌握土壤分布规律与变化趋势,为合理改良与充分利用土壤资源提供科学依据。该地区为暗棕壤,共有五个亚类,九个土属,十六个土种;非地带性土壤有4个土类、九个亚类。

The fertility characteristics of forest soil was analysed according to the results of investigation,The forest region ,soil have certainy characteristics of the terra calcis,the organic matter was accumulated by specific way, the humification is powerful.lts fertility levels is higher than that of lateritic red earth and it is not lower than that of red earth at the same latitude if there are forest.

根据调查研究结果,分析了林区土壤的肥力特点。该林区土壤属褐红壤,具有一定的钙质土性质,有机质有特殊的幂积方式,腐殖化过程强,其肥力水平高于赤红壤,在有林情况下,不低于同纬度的红壤。
