In two representive sites selected from the plains and polders area in Taihu Region, the physical, chemical and mineralogical properties of soils were studied. Results obtained showed that the polder soil association was deeply influenced by anthropogenic horizon and the structure of soil mantle tended to be uniform; the soil association of the plain was greatly influenced by human activity of cultivation, the properties of the soils tended to be varied.

本研究从区域土壤生态系统的观点出发,选择太湖流域二个主要生态区的各一个代表地段作为生态样区。通过代表剖面的理化和矿物分析,研究了土壤组合的特点,并以方格-随机法布置观测和采样点,用趋势面分析了土壤组合内的性态变异规律。表明圩区土壤组合深受人为堆迭层的影响,趋于均一化;平原区土壤组合由于人为耕作等影响,土壤性态发生明显变异。两个组合中有机质和全氮含量随地形增高而下降,全磷含量则有在居民点附近富集的趋势。在目前管理水平下,圩区水稻土肥力水平差异小,其上作物产量的差异不明显,作物产量由管理措施的好坏而决定;平原区土壤组合中,肥力越高的土壤,作物产量的平均值越高,而变异系数越小。由此说明,土援组合的性态变异特点,既受自然因素和人为活动的影响,又影响作物生长,是土壤生态系统水平结构的基础。

In comprehensive improvement of loess plateau, we should persist in combination of tree-grass planting measures with engineering measures. Terracing is one of important engineering measures on slope and field. From the comprehensive investigation of loess plateau in scopes of Gansu prov. and analysis of typical regions, it is obvious that terracing does not only increase productivity of farmland, but also is very effective in waterstorage, trapping sediment and promoting ecological system of soil in positive...

In comprehensive improvement of loess plateau, we should persist in combination of tree-grass planting measures with engineering measures. Terracing is one of important engineering measures on slope and field. From the comprehensive investigation of loess plateau in scopes of Gansu prov. and analysis of typical regions, it is obvious that terracing does not only increase productivity of farmland, but also is very effective in waterstorage, trapping sediment and promoting ecological system of soil in positive direction. So, we must enhance terracing construction, while the stress is being laid on trees-grass planting, and, only in this way, it is possible to improve internal structure of agriculture, develop deversified rural economy and establish a very effective comprehensive water-soil conservation system.

黄土高原的综合治理,必须坚持林草措施与工程措施相结合。而坡面田间工程措施主要是修梯田。作者从对甘肃省黄土高原的综合考察和典型分析中表明,梯田不仅具有明显的增产、增收效应,而且具有显著的蓄水、拦泥、促使土壤生态系统逐渐向良性循环转化的生态效益,在抓种树种草的同时,必须加强梯田建设,才能逐步调整农业生产内部结构,发展多种经营,建立高效能水土保持综合防护体系。

Soil environmental capacity is the maximum tolerable amount of pollutants inputed into a soil ecosystem,which still maintains its normal structure and functions. Mercury compounds have severe toxicity on soil ecosystems and human health, therefore investigation on soil capacity of mercury is of practical significance and theoretical value.This work is focused on soil ecology.

Soil environmental capacity is the maximum tolerable amount of pollutants inputed into a soil ecosystem,which still maintains its normal structure and functions. Mercury compounds have severe toxicity on soil ecosystems and human health, therefore investigation on soil capacity of mercury is of practical significance and theoretical value.This work is focused on soil ecology. Threshold values of mercury in meadow burozem were determined acceding to the comprehensive indexes, which were built up by us, e. g. soil-plant, soil-microbes and soil-water system. The annual capacity and alterable capacity of mercury were calculated with the parameters obtained from ballanced tests.

土壤环境容量是输入土壤生态系统污染物的最大允许负荷,此时该系统仍保持正常的结构和功能。汞对土壤生态和人体健康的毒性颇大,因此研究其土壤容量具有一定的现实意义和理论价值。 本项研究以土壤生态为中心。根据我们建立的综合指标,即土壤-作物、土壤-微生物、土壤-水体系,确定了草甸棕壤汞的临界含量。运用平衡试验所获的参数计算了汞的年容量和变动容量。
