The steppe landscape is dominant but not apparent in its patch and area, and the percentage of the original vegetation of Stipa bungeana steppe is very low in the study area, which is apparently characterized by human disturbance. The diversity and evenness of patches in the study area are higher than those of the steppe landscape area, and the fragmentation and the isolation of the steppe are the highest. The landscape shapes of artificial arbor woods and cultivated lands are the simplest, and the landscape shapes of classical steppe and artificial shrub are in an instable stage.

结果表明：(1)草原景观在其斑块数和面积上虽然仍居首要地位，但其优势并不十分明显，而且该区原生植被本氏针茅草原只占很小的比重，呈现出非常明显的人类干扰特征；(2)研究区斑块的多样性程度和均匀度较高，而面积的多样性程度和均匀度较低，同时，典型草原的景观破碎度最大，景观分离度也最大；(3)景观形态上，人工乔木林和耕地的景观形态最为简单，典型草原和人工灌丛这2种景观类型还处于很不稳定的阶段。

Analysis of sedimentary facies and the multiple proxy indexes indicate that climate have many times dry-cold and warm-wet changes in the desert-loess transition belt since the last interglacial, and environment undergone alternations from warm semi-humid forest steppe, temperate-humid shrub steppe, semi-arid steppe and dry-cold steppe, desert steppe to desert.

地层沉积相及粒度、磁化率、化学元素、孢粉和古脊椎动物化石等气候代用指标的测试分析，揭示了研究区末次间冰期以来气候有过多次干冷、暖湿波动，曾经历了干冷的干旱荒漠、干旱荒漠草原、半干旱干草原、温湿灌丛草原或疏林草原、温暖半湿润森林草原气候环境的交替变化。

The Farming-pastoral Zone in North China was separated into 8 Eco-regions according to the known Eco-region. The dissertation analyzed the regional differences of land use changes from three aspects on dynamic degree , land use degree and the change direction (1)On land use dynamic degree, the dynamic degree of the cropland was the highest in North warm temperate deciduous broad-leaved forest and the lowest in temperate forest steppe; forest land's was the highest in alpine meadow and the lowest in warm temperate forest steppe; grassland's was the highest in temperate forest steppe-bunchgrass steppe and the lowest in alpine meadow; other land's was the highest in North warm temperate deciduous broad-leaved forest－the Huang-Huai-hai plain and the lowest in warm temperate bunchgrass steppe.

结合已有的自然生态区的划分，将我国北方农牧交错带划分为8 个自然生态区，选取土地利用动态度、土地利用程度以及土地利用变化方向等3 个方面的指标对研究区进行了区域分异规律的研究，结果如下：（1）耕地动态度北暖温带落叶阔叶林生态区——北部山地丘陵区最大，温带森林草原生态区最小；林地的动态度高寒草甸生态区最大，暖温带森林草原丛生禾草草原生态区——东南森林草原区最小；草地动态度温带森林草原——丛生禾草草原生态区最大，高寒草甸生态区最小；其他用地的动态度北暖温带落叶阔叶林生态区——黄淮海平原区最大，暖温带森林草原丛生禾草草原生态区—西北丛生禾草草原区最小。
