We have set the experiment in Linhua and Changtin counties, where the mother material of soil is shale purple soil and granite red soil, and it is subtropical climate, the pine growth was restrained and C Horison is exposed. We established grassland with three kinds of different mixture variety consisting of grasses and shrubs, and set runoff plots in the grassland to study the vegetation of mixture variety type for eroded land and the establishing grassland benefit in the soil and water conservation. The result shows that the mixture of grasses and leguminous shrubs is better than mixture of pure grasses or mixture of grasses and leguminous grass. In twenty-three months after seeding, amount of fungi and bacterium of microorganism in soil increases for 5.5 and 9.3 times respectively more than those before; compared with control, the soil nutrients, moisture and organic matter increases apparently, the production of pine growth increases for 3.5 times, the satisfactory result provided a successful method to establish the grassland in wide seriously eroded soil area.

我们在宁化、长汀两县利用三种不同品种组合进行草地建植试验,以探讨严重侵蚀劣地建植草地的草种组合与水土保持效益。该地属亚热带气候,土壤母质分别为紫色土和红壤土。试验结果表明,禾本科草与豆科灌木的组合比禾本科草与豆科草的组合及纯禾本科草的组合好;草地建植23个月后,土壤侵蚀总量比对照减少约91%倍,枯草期低温条件下土壤细菌类和真菌类的微生物数量比对照分别增加5.5倍和9.3倍,土壤速效养分、有机质及水分含量有明显提高,马尾松生物量增长3.5倍。试验取得满意的结果,为广大严重侵蚀劣地建植草地提供一个成功的方法。

This study was made in the yellow-red earth of man-made forests Cunninghamia lanceolata and Finus massoniana in 1984-1988. There is a loam in soil texture. The depth of soil is thinner. The volume weight of soil ranges 0.78-1.35. The total porosity of soil is about 55%-77%, including capillarity porosity about 40%-50%.The coefficent of soil premeability 3.18-5.37mm/mun. The mean annual soil moisture content in 5 years is about 21% -32% of water. The soil moisture content in forests is more than that in the clear-cutting...

This study was made in the yellow-red earth of man-made forests Cunninghamia lanceolata and Finus massoniana in 1984-1988. There is a loam in soil texture. The depth of soil is thinner. The volume weight of soil ranges 0.78-1.35. The total porosity of soil is about 55%-77%, including capillarity porosity about 40%-50%.The coefficent of soil premeability 3.18-5.37mm/mun. The mean annual soil moisture content in 5 years is about 21% -32% of water. The soil moisture content in forests is more than that in the clear-cutting land, but the seasonal variation of soil moisture content in the forest is less than that in the clear-cutting land. The effect of climatical factors on soil moisture content is obvious. According to the mathematical statistics analysis, soil moisture(y) approximates precipitation (x1), air temperature (x2), air humidity (x3), air evaporation (x4) in polyromial regression, its equation is Y = a1x1+ a2x2 + a3x3 + a4x4+a5. According to the analysis of this polyromial regression, the depth of soil moisture content, obviously effected by climatical factors, reaches to 20 cm of the soil in the forests and reaches to 40 cm of the soil in the clear-cutting land.

1984~1988年,在江西省分宜县山下林场的亚热带人工杉木林和马尾松林中,对土壤的水分—物理性质及其水分含量的变化进行了测定,结果表明:本试验区土壤为重壤土,其水分—物理性质较差,有林地土壤含水量较无林地高,且变幅较小。土壤含水率与当地的主要气象要素(气温、空气湿度、降雨量、蒸发量)呈多元回归相关。据回归分析,杉木林土壤水分含量受气候变化影响的土层深度较浅,达0~20cm,而皆伐迹地受气候影响的土层较深,达0~40cm。

In 1984~1990, precipitation, runoff and soil moisture in the 22-year-old plantation of Cunninghamia lanceolata Lamb, and Finns massoniana (Lamb.) Hook, were measured. Some results from 2 small experimental forest watersheds and 2 runoff plots are presented. The ranges of the average annual runoff were 15.648mm to 31.148mm, or 1.245 % to 2.537 % (annual runoff coefficient). Maximum runoff in a time period is about 2.16mm to 24.587mm or 3.07 % to 31.35 % (runoff coefficient). According to the analysis of multi-regression,...
