Research on the evaluation system of new energy development decision in Dunhuang city based on analytic hierarchy process

Abstract

Dunhuang is rich in new energy resources such as solar energy, biomass energy and wind energy, which have great development prospects. However, due to the lack of the objective and scientific evaluation system for the development and utilization of new energy resources in Dunhuang, there have been different opinions and views on the selection of new energy fields that need to be developed first and the development sequence, which is not helpful to the scientific decision-making of new energy development. Aiming to solve this problem, this paper begins from the research status of new energy industry in Dunhuang, takes amount of available resources, land acquisition area, GDP contribution, environmental friendliness, investment cost and policy support as evaluation indicators, and takes biomass power generation, solar thermal utilization, photovoltaic power generation and wind power generation as development targets. The evaluation index system of new energy in Dunhuang is constructed by using the analytic hierarchy process, along with the optimal mode of new energy development in Dunhuang is studied. The study shows that in the evaluation index system of new energy development in Dunhuang, In the evaluation index system, the order of the influence of each index on the weight of the research objectives is the amount of available resources (0.3976) > GDP contribution (0.2684) > investment cost (0.1545) > policy support (0.0876) > environmental friendliness (0.0568) > land acquisition area (0.0350). In the development target layer, the order of the influence of each development factor on the weight of the research object is photovoltaic power generation (0.3535) > solar thermal utilization (0.2525) > wind power generation (0.2306) > biomass power generation (0. 1634). Therefore, Dunhuang should focus on the development of photovoltaic power generation industry. The results provide a abstract reference for the development of new energy in Dunhuang.
