With the highly protection of ecological environment in the global, field road engineering, as one of the important land reclamation projects was given an ecological environmental protection concept. Meanwhile, the rationality of field road layout is also an important index between the land layout and overall coordination of field project. Based on the landscape ecology and the road network standards, this paper introduces the index of Matrix corridor and embedded block in landscape, and some parameter for the density of the network (mesh size) and the capacity of the road links (pavement width). Moreover, with the artificial intelligence and the basic principle of the field, it constructs the knowledge base and rule library for the field road layout, by using genetic algorithm to build the field optional arrangement and evaluation model. Besides, it realizes the road intelligent layout functions in mining area by GIS platform. Usage shows that the system can achieve the intelligent layout and optimization between the main road and minor roads, under the instruction of landscape ecology. Also, it can implement Aided design function for land reclamation engineering.© 2013 American Scientific Publishers. Copyright © 2013 American Scientific Publishers.

In this study a GIS-based decision support system (DSS) was built for selecting proper plant species in dump area revegetation. This was done by integrating a matching model fuzzy pattern recognition (FPR) and a benefit optimization model dynamic programming (DP) into geographical information system (GIS) software (ArcGIS 9.2) as a toolbar (DLL) using ArcObjects in ArcGIS and Visual Basic 6. The DSS consists of database, model base, rule base and parameter weighting database. The parameters come from soil, climate, plant characteristic, ecology, landscape and social. This database includes detailed data about plant types and their properties. The proposed system is able to integrate both the quantitative and qualitative factors together. For the qualitative factors, IF-THEN rules are summarized from the questionnaire survey for the production experts. In this DSS complex problems are solved within program so that proper plant and plant distribution are automatically tracked when the dump area environmental changes. This DSS can help land consolidation managers to analyze and visualize (charts, maps) the possible plant species of dump area revegetation, such as plant characters, proper plant species, benefit of plant and the map for the plant distribution. Finally, a case study is conducted to demonstrate the procedure of the proposed system and identify the suitable proper plant species. Copyright © 2010, TSI ® Press Printed in the USA.

Land rehabilitation can affect the environment of dump areas prominently. For example, it can improve the chemical properties of the soil in the dump. In order to discover the quantitative relationship between land rehabilitation and soil improvement, firstly, 14 kinds of physical and chemical properties of the soil in dumps are compared and analyzed, such as the soil's organic matter content, thickness of the soil layer, total nitrogen, available phosphorus, calcium, magnesium, sulphur and boron, rapidly available potassium, iron, copper, zinc and manganese, and pH. Secondly, according to different waste ages and different rehabilitation ages and based on the theory of water and soil conservation and soil science and ecology resumption, the soil improvement benefit of land rehabilitation is studied by using the method of space as a substitute for time. Finally, this paper discusses the soil improvement benefit evaluation system of land rehabilitation in dump areas initially, then builds a soil improvement benefit evaluation model utilizing the gray relational analysis method. This research can provide the necessary test data, scientific basis and evaluation method for land rehabilitation projects in dump areas. The results show that the soil improvement benefit is directly proportional with the different waste ages and the different rehabilitation ages. In addition, human activity is also an important factor for the improvement benefits of land rehabilitation. © 2010 Elsevier Ltd.

Because of the complexity and diversity of the terrain and cover types in coal mine dump, it is difficult to set up the research points in the wild dump. This paper introduces an embedded GPS and GIS technology and develops portable environmental information acquisition system applied to coal mine dump investigation. The system mainly achieves the functions of soil, vegetation, microclimate sampling layout and information collection. According to the different sampling requirements, the system can draw the layout grid on the base map, which achieving sampling points positioning and information prompting. The environmental information we collected can be transmitted to the remote server real-time through GPRS. Experimental results show that the system provides a viable collection and layout scheme, includes real-time acquisition, transmission, information and data processing. Thus it reduces workload of the sampling and information collection, and it has strong practicality. © 2012 Copyright TSI® Press.
