科尔沁沙地中部沙质灌溉农田土壤全N和有机C含量的垂直分布呈锯齿状，表现为明显的多‘峰谷’性，这种变化与土壤的粘土层/有机质层和沙层交错分布的特点有关。

The vertical distribution of organic C and total N contents in irrigated cropland soil presents a pattern of fluctuation with the alteration of clay / organic layer and sandy layer .

在测定科尔沁沙地小麦凋落物分解率的基础上，对分解残留物中的N、P、Ca和S等元素含量进行了测定与分析。

Based on the measurement of decomposition rate of wheat litter , dynamics of four nutrient elements , N , P , Ca and S , in remained decomposed organic matter of wheat litter had been analyzed quantitatively .

根据1985年和2000年的2期土地利用图形数据，运用地理信息系统（GIS）技术，数理统计方法和景观生态学方法，研究了生态保护背景下科尔沁沙地奈曼旗土地利用及其景观格局的新变化。

Based on digital land use maps of 1985 and 2000 , the land use and landscape change under ecological protection in Naiman county , Horqin Desert , were studied , exerting geographical information system ( GIS ), statistics and landscape ecology methods .

科尔沁沙地的过度开垦对沙漠化程度的影响要大于牧业活动，多元回归分析表明，沙漠化程度与人口密度、耕地指数和载畜量的复合关系有着最高的相关系数（R2为0953）。

Multi-regression analysis showed that multi-relationship of the desertification degree and the population density , cropland indices , and grazing capacity was closer and had highest correlation coefficient .

依据生长期土壤水分状况和水分平衡要求，科尔沁沙地小叶锦鸡儿灌丛适宜密度应为2m×2m。

According to the soil water status and water balance theory , the appropriate planting density of C. microphylla shrubs in Horqin sand land should be 2 m × 2 m.

通过田间小区取样，研究了科尔沁沙地小叶锦鸡儿（Caraganamicrophylla）人工固沙林0～50cm土层在0、5、10、22年的时间序列上土壤有机碳动态。

A field study was conducted to study soil organic carbon dynamics in Caragana microphylla stands in an age sequence of 0 - , 5 - , 10 - , and 22-yr plantations in the Horqin Sandy Land , north China .

研究了科尔沁沙地封育5a后退化沙质草地自然恢复过程中土壤&植物系统的变化特征，同时分析了土壤性状与植物特征之间的相互影响程度。

The variation features of soil-plant system in the natural restoration processes of degraded sandy grassland in the Horqin sandy land after 5 years of exclusive grazing by animals are studied . In the meantime , the interacting degree between soil properties and plant characteristics are analyzed .
