环境生态学

We put forward the introductive research between the human activities and the diversity of species and the results obtained in the paper is useful to enrich the content of landscape ecology and the protection of endangered species.

本文的创新在于：提出了栖息地增加对物种多度影响的模式、生境重叠的模式以及物种和环境之间相互作用(即环境容量的变化对物种多度的影响)的模式；开展了人类活动与物种多样性的初步研究，对丰富景观生态学和物种多样性的保护具有一定的学术意义和应用价值。

Basing on the carefully analysis of the theoretical technoledge project practice in domestic and foreign open pit coal mines,applying the theory such as ecology mining penology farming and forestry the conservation of soil and water ,and environmental project etc.

本文在认真分析、总结国内外露大煤矿土地复垦的理论和工程实践的基础上，应用生态学、农林学、土壤学、采矿学、水土保持、环境工程等多门学科的理论，详细论述了露天煤炭开采对区域环境的影响，提出了应用生态系统的演变规律来指导露天煤矿的土地复垦，从而实现了把复垦区水土保持和土地最终利用方向有机结合。

Modern approach methods of geography, ecology, quantitative analysis, expert integration, remote sensing image analysis and geographical information system were combined to reveal the matters in this paper. The eco-geographical background of the research area and the research work studied by other scholars were comprehensively expatiated. The temporal and spatial variation of precipitation and soil moisture, vegetation and soil distribution, and land use/land cover were compared as well. On the basis of foregoing analysis, the eco-geographical differentiation was discussed. According to principles and indicators, with extension engineering method and integrated analysis, the physical geography boundary between subhumid and semiarid areas were demarcated. By using remote sensing image analysis, wavelet analysis of the perennial precipitation and temperature, and the comparison of temporal and spatial variation of the desertification, this paper accounted for the regional response to global environmental change and suggested the dominant environmental problems.

本文采用了地理学与生态学相结合、定量分析与专家集成相结合、遥感图像解译和地理信息系统相结合的方法，对研究区的生态地理背景和已有研究工作进展情况给予了全面的分析和阐述；通过对区域水分条件（大气降水、土壤水分条件）、植被、土壤、土地利用／土地覆被状况等环境要素的时间与空间特征的对比分析，探讨了研究区内部生态地理特征的差异；在一定的原则指导下，通过建立指标体系，以可拓工程方法和模型为支撑，经过综合分析确定了研究区内半湿润、半干旱区界线划分方案；通过遥感图像解译、典型站点多年降水与温度的小波分析、土地沙漠化时空变化的对比分析等，说明了研究区域对全球变化的响应；表明了该区域所面临的主要环境问题。

Autecology The study of the interactions of an individual organism or a single species with the living and nonliving components of its environment.

ABSTRACT This dissertation, based on the theories of geography, ecology, economics, sociology and environmental sciences, has analyzed the impact of transition between cultivation and pasture animal husbandry on the mechanism of desertification in Kerqin Sandy Region, of which behavior mechanism of local people was emphasized. The changing direction of integrated land desertification control strategy in semi-arid regions was discussed after having explored the primary reasons of estrepement, overgrazing and excessive firewood gathering. Followings are the main research works having been done.

本文选取科尔沁沙地作为研究区域，以两种最主要的土地利用方式、也是两种最主要的生产方式——农、牧业作为研究对象，依据地理学、生态学、经济学、社会学与环境科学的基本理论与方法，基于现有研究资料的系统整合，结合野外调查的结果，从更加综合的角度，来研究农、牧业选择变化对沙漠化过程的影响机理，从农、牧业选择变化的角度来揭示&滥垦、滥牧、滥樵&的本质，进而寻求中国北方半干旱地区生态环境综合整治的对策。
