Abstract: The land utilization engineering is a branch of engineering which sets up a new ecological balance by adopting the combination of engineering and biological measures to meet the needs of the development of productiveforces and economic reconstructions. All these should follow the principle of ecological balance, through the activities of production. Thus, the emergence and progress of the land utilization engineering usually coincides with the needs of productive development. This branch of engineering started at Xia and Shang Dynasties about several thousands of years ago. Since the founding of New China, land utilization engineering has been rapidly developed.The contents of this engineering are as follows: Reclaim land to increase agricultural area; Use the land resources more reasonably; improve the land utilization condition to build up a new ecological balance; protect the land from new destructiveness.Land utilization engineering is different from other sciences, but it is quite related to other sciences. Land utilization engineering is to study the internal relations between all the ecological factors synthetically while other sciences study their own different factors.
