Taking Huize County as an example, the paper analyzed the landscape structure(landscape element structure, landscape type structure, landscape spatial structure, landscape succession structure) and the relations between landscape structure and land use. It was pointed out that the agriculture should be developed in harmony with the landscape structure in the study area.

MANDELBROT enunciated the uncertainty of the length of a coastline in his paper"How long is the coastline of Britain?"published in "science" in 1967. The fractal concept was presented for the first time in that paper and has been applied to many fields ever since. According to the fractal theory and conditions of fractal research of coastline,the controls of faults and biologic function on the fractal character of coastline are preliminarily discussed on the basis of GIS in this paper . Finally,some significant conclusions are drawn:1)the faults control the basic trends of coastlines of two study areas;2)the fractal dimension of coastline of Taiwan is smaller than that of Changle-Lufeng,because the faults of Taiwan more intensely control the trend and fractal dimension of the coastline;3)the larger the fractal dimension of the faults or the major faults,the more the controlling effect of them on the trend and fractal dimension of coastline; 4)the larger fractal dimension of the coastline of Changle-Lufeng indicates that the biologic function intensely shapes the coastline. In a word,the controls of faults and biologic function on the fractal character of coastline are discussed with a case study of China in this paper,it can be seen that faults and biologic function both have influence over the trend and fractal dimension of coastline,the fractal mechanism of coastline of two study areas may be so.

Modeling land use/cover scenario changes and its potential impacts on structure and functions of ecosystem in typical regions are helpful to understanding the interactive mechanism between land use/cover system and ecosystem. Based on the analysis of the existing land use/cover simulation and forecast models, a land use/cover scenario dynamics model by the integration of System Dynamics (SD) model, Back Propagation Neural Network (BPNN) and Cellular Automata (CA) model is developed with land use/cover scenario changes in northern China in the next 30 years and simulated in this paper. The model is to simulate the land use/cover scenario demands by using a SD model at first, and then allocating the land use scenario patterns at the local scale with the considerations of land use/cover suitability, inheritance ability and neighborhood effect by using BPNN-CA model to satisfy the balance between land use/cover scenario demands and supplies. It integrates the advantages of SD, BPNN and CA. Macro-driving factors and the micro-spatial pattern are also fully taken into account. The BPNN simplifies the identification of the factors’ weights used in CA model and improves the reliability of the simulation results. The simulation accuracy of the model developed in this paper was found to be about 74%. It suggests that the model has the ability to reflect the complexity of land use/cover system at different scales to some extent and it is a useful tool for assessing the potential impacts of land use system on ecosystem. The simulated results also indicate that the urban land, water area and forest will increase significantly, and farmland and unable land will decrease gradually. Obvious land use/cover changes will take place in the farming-pastoral zone and the southeast area of northern China.

In the recently 20 years, grassland vegetation coverage change rapidly in Inner Mongolian Plateau, it both related to global climate change, and also closely related to is social and economic system in Inner Mongolia in the last 30 years. In this paper, Based on the relation between human and land theory as the guide, by using GIS and field survey method, with the Yihewusu Gacha of Abag Banner for research area, to take the four seasons pasture of districting rotational grazing as a unit, analyzes the changes of grassland vegetation coverage in the GaCha nearly 20 years. Results shows that [1]grassland degradation（grassland vegetation coverage decreased）;[2]the change of grassland vegetation coverage of districting at a quarter of rotational grazing is different, Vegetation coverage of summer pasture is highest, while the vegetation coverage of winter pasture is lowest. The analysis results showed that at present, "districting at a quarter of rotational grazing" one of more economical and effective method of protection natural grassland and restoration degraded grassland.

对南通市河网景观格局与地表水污染的关系进行探讨。在对南通市的河网景观格局进行定性分析的基础上,设计并定量计算了南通市河网景观格局指标,据此分析了不同排污功能河流的景观格局特点:①就污染程度来说,工业排污河流最为严重,生活排污河流次之,农业排污河流水质最好;②就河流污染物分布来说,工业排污河流最不均匀,生活排污河流次之,农业排污河流最为均匀。这与实测分析结果基本一致,说明城市河网景观格局是影响污染物分布、运移的主要因素之一。
