This paper analyzes the growing need of information technology to conserve water resources, capable of storing, integrating, and displaying geographic information. At present, the Geographic Information System is not only limited to cartography but also related to various data management such as natural resource management, environmental impact assessment, and etc. The Information technology coupled...
Existing studies showed that ecosystem services most focused on certain types of wetlands, such as marine, marsh, and lake, while river wetlands were not fully studied. In order to build a general framework to map and value the wetlands ecosystem services, this study made a spatial analysis on it in Huanghuaihai region, through horizontal and longitudinal dimension (2d), as well as added vertical...
River networks (including rivers and drainages) ecosystems in many irrigation districts are getting worse as the development of farmland irrigation. Ecosystem service values can reflect the deteriorating situation of river networks ecosystems. In this paper, a classification of river network ecosystem service values of irrigation district is presented and suitable estimate methods are recommended...
Dahuangpuwa detention basin is an important flood control project in Haihe River Basin. It provides complex ecological functions and services. Examples of the ecosystem's services are flood control, water purification, biodiversity, production output and recreation. Based on field surveys and research of the study area, the economic values of the main ecosystem services in Dahuangpuwa are computed...
Based on the phantom interpretation data of land TM/ETM of 1996 and that of 2006, this article analyzed the land use and land cover change of ChangBai Mountain area in the recent 10 years, and calculated the change of ecosystem service value resulted from this change. During the 10 years, LUCC of Changbai Mountain area had changed fiercely, the paddy field, the forest land and the wetland were in...
A System-Wide Monitoring (SWiM) program is currently in development to provide an approach for integrated design, implementation, and reporting for the National Marine Sanctuary System. It will serve individual marine sanctuaries, regional networks of sanctuaries, and the collective system. It allows for tailored monitoring in all sanctuaries, providing information critical to management, while also...
