| Research on Wilderness Identification and WildernessProtected Area—Taking Gansu as an Example |
| ZHANG Kai,LI Wei,QI Jianwu |
| Abstract: |
| Wilderness has important value in mitigating climate
change crises and protecting biodiversity, and this concept is
constantly developing globally. This article takes Gansu as an
example and combines public perception surveys to establish a
wilderness recognition index model from four aspects: biophysical
naturalness, human interference, distance, and appearance integrity.
The Wilderness Map of Gansu Province (WQI) is obtained through
index calculation, normalization, and stacking using GIS kernel
density (KDE) and Boolean stacking operations. The results show
that the quality of wilderness in Gansu Province shows a spatial
trend of "high in the west and low in the east", and the quantity
shows a spatial trend of "more in the west and less in the east"; there
is a positive correlation between wilderness quality and altitude;
the natural base of the wilderness is mainly composed of Gobi and
desert ecosystems, with obvious ecological fragility; 70% of highquality
wilderness is still outside protected areas, and there is an
urgent need to strengthen management. Based on this, this article
proposes the construction of a classified and graded wilderness
protection system and wilderness protection context. The research
can provide reference for wilderness identification indicators,
methods, and protection methods, as well as for the construction of
wilderness protection systems. |
