Abstract：Such protected structures as greenhouses provide good environmental conditions for vegetable growth and quality．To improve and build new-typed，high cost-effective protected structure combining both farm machines and techniques is the essential way to push forward the high-quality development of protected vegetables．In this article，we summarized the status quo of old-typed greenhouse and tunnel structures in northwestern，northern，northeastern and eastern China．We stated the different types of the commonly-built new single greenhouses，tunnels and multi-span greenhouses，the types of wall materials for greenhouses，heat preservation covering materials，and the types of energy utilization．We analyzed the major existing problems in the protected structures and environmental control of China’s vegetable growth． In this article we also proposed to choose the greenhouse designing structures according to regional environment，crop differences and the managing grower，and to integrate the new structures，new equipment and new materials in protected structure designing．We suggest that greenhouse transformation schemes be made so as to reduce the fund for building new greenhouse；that protected facilities with excellent performances be built under effective organization and with the leading of good policies，and that more projects and programs for technological breakthrough be approved to solve the key problems existing in protected structure designing and building．
