WIPO Patent Application WO/2023/213142
Kind Code:
A1
Abstract:
Disclosed are an ecological quality evaluation and partitioning method and apparatus based on improved remote-sensed ecological indices. The method mainly comprises: constructing an improved remote-sensed ecological indices model, wherein the model comprises a green index, a humidity index, a dryness index, a heat index, and a forest service index; performing calculation on the green index, the humidity index, the dryness index, and the heat index for a current period and the newest forest service index of a region to undergo evaluation according to the improved remote-sensed ecological indices model to obtain improved remote-sensed ecological indices of the region to undergo evaluation for the current period; and determining the ecological quality level for the region according to the improved remote-sensed ecological indices, and delimiting an ecological restoration region. Supplementation of the forest service index facilitates further assessing the positive or negative influence of the type and surface area of vegetation in an evaluated region on the local ecological environment and ecological background in an area having higher vegetation coverage, and the accuracy of regional ecological quality evaluation and the identification of the ecological restoration regions are further improved.
