Problems solved by technology
[0004] Most of the current wealth index evaluation models are constructed based on statistical data, but the evaluation models based on statistical data are severely limited by the availability of statistical data. It is more difficult to collect statistical data for district-level wealth index evaluation. In addition, different The statistical data standards of districts and counties may be inconsistent, so it is difficult to apply the traditional statistical data-based district and county wealth index evaluation model to the evaluation of SDG 1 in Chinese districts and counties

Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0037] Such as figure 1 As shown, a method for evaluating the wealth index of districts and counties based on multi-source remote sensing data, the specific steps include:
[0038] (1) Based on the global indicator framework of the Sustainable Development Goals, taking the existing affluence index evaluation index system as a reference, and taking into account China's national conditions, the localized index system of SDG 1 is proposed for districts and counties. SDG 1 is the first SDGs of the United Nations Sustainable Development Goals One goal is no poverty, and carry out dimensionless processing and weight assignment on the selected indicators.
[0039] The specific steps are:
[0040] (1-1) There are 7 SDG 1 sub-goals in SDGs, as shown in Table 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.a, 1.b, among which the SDGs global indicator framework includes 13 SDG 1...

The invention discloses a district and county surplus index evaluation method based on multi-source remote sensing data, and the method comprises the following steps: firstly, providing a district and county SDG 1 local index system through the existing surplus index evaluation index system design based on a global index framework of a sustainable development target; secondly, extracting feature factor data of social economy, land coverage, ecological environment, accessibility, landform and structural texture variables based on multi-source geographic data such as night light images, land coverage, vegetation indexes, road network data, digital elevation models and daytime remote sensing images; thirdly, constructing a district and county SDG 1 partial least square model based on the characteristic factors; and finally, model verification and precision evaluation are carried out in combination with statistical data of counties and districts in China, and factor correlation analysis is carried out. According to the method, the China district and county SDG 1 evaluation model is constructed in combination with multi-source geographic data for a united country sustainable development target framework, and reference is provided for country revitalization and regional balanced development.
Description
technical field [0001] The invention relates to a method for evaluating the wealth index of districts and counties based on multi-source remote sensing data. Background technique [0002] The United Nations Sustainable Development Goals (SDGs), specifically including 17 sustainable development goals, the first goal of no poverty (SDG 1) is to eliminate all forms of poverty in the world, achieve the goal of becoming rich, and point out the eradication of poverty Achieving prosperity must go hand in hand with strategies such as prosperity index assessment monitoring and development progress. [0003] The global SDGs indicator framework clarifies the techniques and methods for target assessment, is universal and comprehensive, and provides a unified indicator system for countries to conduct SDG 1 assessment and monitoring. However, considering China's development stages and different levels of data mastery, how to effectively design the SDG 1 indicator system for China's distr...
