This paper is the result of urban geological survey engineering.[Objective] This paper aims to develop the study of natural resources endowment in ecological security, environmental protection, agricultural production and urban construction in Chengdu-Deyang-Meishan-Ziyang urbanization construction area, and propose the protection strategy of territory development preliminarily. [Methods] This paper is carried by systematically organizing the research results of previous geological surveys in the study area. [Results] The research shows that the resources and environmental conditions of the Chengdu-Deyang-Meishan-Ziyang urban groups are generally good, and the most important ecological protection area presents the spatial characteristics of "northeast orientation and three corridors". In the past 30 years, nearly 80% of the area has maintained good ecological space. In addition, the ecological space increase area is slightly larger than the decrease area, and the ecological function is strengthened year by year. The atmospheric environment is relatively good, the water quality of rivers and groundwater is on average, the water quality of rivers presents the spatial characteristics of “good upstream and poor downstream”, and the groundwater which is Grade 5th of NSWS presents the spatial characteristics of “concentrated in urban area and scattered around urban area”. Suitable areas for agricultural production are widely distributed, concentrated and contiguous, with good combination of water and soil resources overall good soil nutrients and environmental quality. Most areas contain selenium, and some are selenium-rich areas. Suitable areas for urban construction are also widely distributed, with good endowment of water and soil resources, but those areas are at the risk of earthquakes and geological disasters. [Conclusions] Based on the similarity of natural geographic patterns, it is suggested that the Chengdu-Deyang-Meishan-Ziyang urban groups should form an integrated land space development, and protection pattern create a regional ecological pilot demonstration area. It also needs to establish a concentrated and contiguous high-standard farmland demonstration area to avoid natural disasters. It is suggested to optimize the spatial pattern and create a multi-center, networked and group-style urbanization system.
