Quality is one of the important indexes. Two mainstream theories guide us to realize the industrial sustainable development: mainly the circular economy and sustainable manufacturing are introduced. The basic characteristics of the sustainable manufacturing are introduced, and that quality management is important contents of sustainable development is indicated. Based on circular economy and sustainable manufacture theories, the drawbacks in the existing quality management models are analyzed. The requests that satisfy the big system "environment- society - economy" are summarized to build up a model. A Chinese traditional cultural principle is applied and the relevant contents are sublimated as the platform to set up the model. The new quality management concept models are put forward "T- D- R" three-dimensional structures and "ecological quality loop" model, from which the new quality concepts are formed The paper elaborates the contents and the process of setting up the models. The big quality problems of the system can be handled by the new quality concept and model that are validated in practice. 展开更多

Accurate quantification of tree populations within regions is critical for evaluating forest ecosystem conditions and developing effective forest management strategies[1].High-quality tree census data,collected through field surveys and remote sensing technologies,is fundamental to China's sustainable development and environmental conservation initiatives.This data facilitates the monitoring of forest structural changes,carbon sequestration dynamics,and ecosystem health evaluations.Notably,China maintains the world's largest managed forest area,achieved through comprehensive national afforestation and reforestation programs[2,3].Consequently,precise tree enumeration is crucial for formulating effective forest management policies,monitoring and protecting wildlife habitats,and preventing natural disasters in China. 展开更多
