【摘要】 地理信息系统(G IS)作为集计算机科学、地理学、环境科学、城市科学、空间科学、信息科学和管理科学为一体的学科,可为水土保持规划设计与管理提供强有力的技术手段支持。在介绍了G IS在水土保持规划设计中的应用背景和目标的基础上,详细介绍了数字高程模型和时态G IS这两项关键技术在水土保持规划设计中的应用。阐述了如何根据数字高程模型自动生成小班的高程、坡度和坡向,以及利用时态G IS对土地利用规划情况、规划治理措施完成情况等进行动态模拟分析的原理。更多还原

【Abstract】 Being as an integrated discipline of incorporating the sciences of computer,geography,environment,urban,space,information and management,GIS can provide powerful technical support for the planning,design and management of soil and water conservation.The paper introduces the application of the two key techniques of digital elevation model and time posture GIS to the planning and design of soil and water conservation in a detailed way based on the application background and objectives of GIS to the planning and design of soil and water conservation.It elaborates that how to automatically generate elevation,slope,slope direction of a sub-lot and how to dynamically simulate and analyze the principles of land utilization planning and the completion of planning and control measures by utilizing time posture GIS.更多还原
