Results show that there is remarkable correlation between the land use types and SOM. From1981 to 2000, the content of SOM increased in the whole area mainly because of the transformation from virgin grass land to cultivated land and increase of irrigable land. The average content of SOM increased by 28% and increased from 9.64 g/kg to 12.35 g/kg. Then the household changed their land use way by driven of interest and do not increase additional input anymore.

研究结果表明：土地利用类型及土地利用方式的转换对土壤有机质含量产生重要影响。1981～2000年，荒草地向耕地的转换以及因灌溉设施的完善而引起水浇地面积的增加使得整个研究区域土壤有机质含量普遍增加，有机质含量平均值从9.64 g/kg增加到12.35 g/kg，增加了28％；在利益的驱使下，农户改变了土地利用方式，不再向种植粮食作物的土地追加投入，研究区域土壤有机质含量平均值由12.35 g/kg降低到11.46 g/kg（2000～2006年）。

The results showed : The way of this village land using is relatively complicated, and the area of cultivated land accounts for 52. 97 percent of the whole area of the land, and the rate of land cultivation and planting is relatively high, but the area of dry land accounts for largish proportion and its productivity is relatively low.

研究中选取了红水河流域内某一个具有代表性的村进行了简单的景观格局分析，其结果表明：该村土地利用方式比较复杂，耕地占土地总面积的52.97%，土地垦殖率较高，但旱地占相当比重，其生产力较低。

In order to keep the food supplies safe, the authors forecasted the amount of the cultivated land in future using the Lindo model, decompounded the basic farmland index using the method of entropic coefficient, selected the cultivated land into basic farmland using the method of approaching perfect point.

为保证粮食安全，运用Lindo模型预测了规划期的耕地数量，运用熵权系数法等方法进行了基本农田的指标分解，并运用逼近于理想点的方法划定基本农田。

The results show that the period of vegetation restoration significantly influences soil basal respiration, which logarithmically increases with vegetation recovery time.

结果表明：土壤基础呼吸随植被恢复年限增加呈增加趋势，土壤呼吸强度和累积呼吸量都表现为植被恢复73年和78年较高，而耕地和植被恢复3年最低。

The effect of harvesting height on the grass yield and quality of two varieties of Lolium multiflorum was studied and the result showed that the different harvesting height greatly affected the fresh yield, dry mater yield, quality and growth characteristics.

多花黑麦草Lolium multifolium具有很强的再生性和耐刈性，为了确定最佳的刈割利用方式，在有限的耕地中获得较高的产量和效益，采用小区试验的方法，研究了不同刈割高度对多花黑麦草特高和杰威产草量和品质的影响。

The Chilean government allegedly used these tear gas canisters in their attempt to subdue Mapuche Indians who have been burning farms and equipment and violently seizing land from timber companies and other large property owners.
