摘要
Maintaining ecosystem balance and realizing the strategic goal of sustainable development are key objectives in the field of environmental sciences. Accordingly, drawing ecological red lines in sensitive and vulnerable environmental areas and important ecological function areas, determining the distribution range of ecological red-line areas, providing scientific guidance for developmental activities, and effectively managing the ecological environment are significant work tasks supported by policy guidance from the State Council and from knowledge gained in educational circles. Taking the Chishui River Basin in Guizhou as the study object, this research selected water and soil loss sensitivity, as well as assessments of karst rocky desertification sensitivity as background assessments of the eco-environment. Furthermore, the functions of soil conservation, water conservation, and biodiversity protection were integrated with exploitation-prohibited areas, and an organic combination of ecological needs and social service functions was created. Spatial comprehensive overlay analysis and processing revealed that the combination marked nine major ecological red-line areas in a total area of 5,030.58 km(2), which occupied 44.16% of the total basin area. By combining the current eco-environmental situation of the Chishui River Basin with the marked out red-line areas, this research proposed corresponding ecological red-line area management suggestions. These suggestions are expected to provide a scientific foundation for eco-environmental protection and subsequent scientific research in Chishui River Basin.
