Resource-based cities need an ecological quality developing way. This paper, in terms of CNKI's 2011 to 2020 Chinese references, uses CiteSpace to study the changes of hot research points regarding China's resource-based cities' quality development by means of visualized key word frequency with results showing "transformation", "upgrading" and "sustainable development" are the top key words, suggesting a shift in hot research points from sustainably long-term mechanism, low-carbon transformation path and modes, eco-transforming efficiency evaluation to green development. As quality development and new conception is heading its way, quality development catches much attention after 2017. This paper defines the connotation of resource-based cities' quality development from green, coordination, smart and livelihoods with objectives to ecological transformation, innovative development, smart ways and improving livelihoods. Economic quality is used to measure the urban transforming capacity. Innovative pathways to quality transformation in resource-based cities are presented from resource environment, technology, regional coordination and livelihoods. This paper concludes that construction of specific and oriented measurement will be the future research hot topics, ecological development and smart transformation is the direction. New information technology will reform the industries, ecology, management and capital supports. Smart ecological construction helps create breakthrough in resources environment, technology, regional coordination and livelihoods, favorable for resource-based cities getting out of dilemma and heading for a quality development.

Verification of environmental costs in shale oil and gas development is meaningful for government to make appropriate environmental policies, for petroleum companies to estimate development benefits and to study environment-friendly development technologies. This paper, based on related references and some research achievements regarding environmental cost, studies its components, confirmation basis, confirmation standards, and formation conditions combined with its impacts on environment, and discusses subjects setting, capitalization and expenses accounting process. Environmental cost confirmation in shale oil and gas development is complicated due to its diversified involvements, vast contents and long-term and hidden impacts on environment, which requires governmental guidelines.

Development of shale oil-gas largely impacts the water environment from mass consumption of water resource and potential water pollution, so it is necessary to protect the water environment during shale oil-gas development. In this paper, according to the requirements of water environmental protection, the protection shall be comprehensive, predictable, periodic, and regional. Based on the analysis of the water environmental protection laws, policies and regulations, the existing documents need to be selected, combined and optimized to reach the requirements of water environmental protection. This paper presents a matrix of water environmental protection for shale oil-gas development based on responsibility majority and means from water resource consumption and prevention of water pollution.
