- 摘要:
- 土壤侵蚀不仅严重地破坏了以土地资源为主的自然资源，还会造成严重的生态环境问题，对可持续发展构成极大威胁。采用Visual Basic 6.0语言和ArcObjects组件库，以COM组件的思想和关键技术为基础，构建土壤侵蚀模型（RUSLE），并以岳西县为试验区域，进行了土壤侵蚀的分布预测。结果表明：所构建的模型具有较强的实用性，使用该模型可以快速有效地对不同试验区域进行土壤侵蚀分布预测，为政府部门进行水土保持规划提供科学依据和决策支持。
- Abstract:
- Soil erosion not only seriously destroys the land-based natural resources, but also causes serious ecological and environmental problems. A great threat to sustainable development was caused by soil erosion. In this paper we will adopt the Visual Basic 6.0 language and ArcObjects component library to construct the Universal Soil Loss Equation (RUSLE) based on the thoughts and the key technology of the COM components, and take the Yuexi county as a study area, predict the distribution of soil erosion. The results show that the model has strong practicability. This model can be used to predict the distribution of soil erosion effectively in different study areas. A scientific basis and decision support for soil and water conservation planning could be provided to the department of government.
