Economic development and energy demand analysis method and device based on drainage basin

Abstract

The invention relates to an economic development and energy demand analysis method and device based on a drainage basin. The method comprises the following steps: acquiring night light data of the drainage basin and provinces and cities passed by the drainage basin within a preset time period; carrying out correction processing on the night light data to obtain night light images of the drainage basin and the provinces and cities through which the drainage basin passes; determining a thermodynamic diagram corresponding to the drainage basin according to the night light image, and performing economic space aggregation analysis on the thermodynamic diagram to obtain an analysis result; and determining the spatial-temporal pattern evolution trend of economic development and energy consumption of the drainage basin and the provinces and cities passed by the drainage basin according to the analysis result. Through the technical scheme, the related close relationship among economic development, energy consumption and drainage basin elements is disclosed, and a relatively objective reference basis is provided for research of the economic pattern and the energy consumption pattern of the Yellow River drainage basin.

Description

technical field [0001] The present disclosure relates to the technical field of watershed management, in particular to an analysis method and device based on economic development and energy demand of a watershed. Background technique [0002] The Yellow River Basin is a complex giant system, which is composed of river subsystem, ecological environment subsystem and human economic subsystem, involving elements of nature, economy, society, ecology, energy consumption and other aspects. Competition, gaming and other relationships provide a basic guarantee for solving major national problems. As an important part of it, the human economic subsystem mainly involves factors such as economy, tertiary industry, and population. The conventional evaluation model is based on a single indicator of GDP. How to objectively evaluate the development of its spatial pattern requires a new method and objective indicators to support the study of economic development trends. [0003] Existing ...

Problems solved by technology

Scholars at home and abroad have conducted a lot of research on this, mainly focusing on the extraction and expansion of urban spatial information, the construction of urban spatial characteristic light numbers, population density and heat island effects, economic development, power energy consumption, and urbanization. It has not been applied to fields such as river basins in terms of ecological environment impact research, etc.
