Method and device for evaluating suitability of seal habitat

Abstract

The invention relates to the field of animal habitat evaluation, and discloses a method and device for evaluating the suitability of a seal habitat. The method comprises the following steps: acquiringa plurality of evaluation factors influencing the suitability evaluation of the seal habitat and data thereof; performing gridding processing on the data to form a plurality of evaluation factor griddistribution diagrams comprising a plurality of evaluation factor grid units; establishing a seal habitat suitability evaluation model on the basis; calculating according to the model to obtain the snoopard habitat suitability indexes of a plurality of evaluation factor grid units; grading the suitability indexes to obtain a grading result; and evaluating the reasonable degree of the grading result according to the plurality of evaluation indexes. The model established by the method provided by the invention is more reasonable in structure, so that a model evaluation result has a good practical application value, and the protection and planning of a seal habitat are facilitated; and the grading result of the suitability index of the seal habitat is reasonably evaluated according to a plurality of evaluation indexes, so that the comprehensiveness and the reliability of the evaluation can be improved.

Description

technical field [0001] The invention relates to the field of animal habitat evaluation, in particular to a snow leopard habitat suitability evaluation method and device. Background technique [0002] Most of the evaluations of the suitability of wild animal habitats in the prior art focus on animals that have received widespread attention, such as giant pandas, crested ibis, red-crowned cranes, Tibetan snow pheasants, golden monkeys, Siberian tigers and other wild species, and have accumulated a wealth of research As a result, the current habitat suitability evaluation of wild species mainly uses MaxEnt model, ecological niche model, PCA and AHP, entropy weight method, generalized additive model, multi-source remote sensing satellite data fusion method, etc. for evaluation. However, there are few research methods for evaluating the suitability of the snow leopard's habitat, and the MaxEnt model is mainly used for evaluation. The accuracy of the MaxEnt model in predicting th...

Problems solved by technology

[0003] However, the MaxEnt model has the problems of black-box implicit relationship and poor model interpretation, and needs to use the spatial distribution data of known species as a limiting condition, which cannot control the internal operation of the model, which is not conducive to the protection and planning of the habitat of snow leopard species; in addition, When using the MaxEnt model in the prior art to evaluate the suitability of the snow leopard's habitat, the selected evaluation factors include ecological environment factors, topographical conditions, annual average temperature, etc. Main interference factors such as soil extraction and soil extraction are included in the scope of evaluation factors, and these human activities are also important factors affecting the suitability evaluation of snow leopard habitats, resulting in unreasonable model structure and low practical application value of evaluation results
