Assessment Method and Application of Human Disturbance by Remote Sensing in the Biodiversity Conservation Priority Area
In China, the biodiversity conservation priority area is an ecological protection system that promotes and enhances the ecosystem and biodiversity. Methods, which are based on the remote sensing data with a high temporal/spatial resolution and wide coverage and are designed for the supervision of human disturbance in the biodiversity conservation priority area, are currently ex-pected to be established. The quantification and specialization of human activity intensity are the key issues for a supervision sys-tem to the environmental protection department on biodiversity conservation. Human disturbance index was proposed to achieve the fast dynamic monitoring of biodiversity conservation priority area. Through establishing the new index system and assessment method, and extracting and calculating the spatial distribution data by raster calculation function of geographical information sys-tem, the degree of human disturbance and dynamic change is assessed by the proposed index system using the GIS method. Firstly, according to the necessity of supervising the biodiversity conservation priority area, the classification system for human disturbance was established to describe its type and spatial pattern. Secondly, the human disturbance index system, which was derived from the classification data, was established to achieve a deeper level of assessment on human disturbance. Then, in order to determine the level of human disturbance, the model and method for disturbance assessment of biodiversity conservation priority area was estab-lished. The human disturbance index (HSI) was calculated based on the main monitoring index. The five-level disturbance assess-ment was used to differentiate the disturbance degree. Finally, the biodiversity conservation priority area in western Guangxi and southern Guizhou was taken as a case study to validate the proposed method. The results revealed the potential of this method to be applied to various biodiversity conservation priority areas. This method and technique process can provide a technical support to biodiversity conservation.
