美国景观设计专业包含两个专业方向，即景观规划(landscape planning)和景观设计(landscape design)。景观设计学与建筑学、城市规划、环境艺术、市政工程设计等学科有紧密的联系，而景观设计学所关注的问题是土地和人类产外空间的问题(仅这一点就有别于建筑学)它与现代意义上的城市规划的主要区别在于景观设计学是物质空间的规划和设计，包括城市与区域的物质空间规划设计，而城市规划更主要关注社会经济和城市总体发展计划。由于中国景观设计发展滞后，中国目前的城市物质空间规划设计仍然由城市规划专业所担当。只有同时掌握关于自然系统和社会系统双方面知识、懂得如何协调人与自然关系的景观设计师，才有可能设计人地关系和谐的城市。
