Abstract: In order to clarify the spatial distribution characteristic of NPAs, to promote the integration of NPAs in the northeast of China, and to provide support for the NPAs system construction dominated by national parks, this article took the NPAs in the northeast of China as the research object, by using the mathematical statistics and spatial analysis function of ArcGIS, the spatial distribution characteristics of 593 NPAs of 9 types in the northeast of China were studied. The results showed that: 1) the geographical distribution pattern of NPAs was aggregation, dense in the southeast and sparse in the northwest. The Liaodong Peninsula and Bohai Rim region, Changbai Mountain region, Zhangguangcai Mountain region, Big Heishan mountain region, and Lesser Khingan Mountains region are the high-density areas for the construction of NPAs. 2) Most of the NPAs in the northeast of China were distributed in low-altitude areas, and 291 of them were distributed in areas below 300 m above sea level, accounting for 49.07% of the total. The Huang Bohai rivers basin, the Huntai river basin, the Yalu river basin of the 15 secondary watersheds in the study area, were the highest area in the distribution density of NPAs. In the 20 tertiary nature conservation integrated geographic areas, Liaodong Peninsula with deciduous broad-leaved forest and wet areas, Long Gangshan with needle mixed forest areas and Yanshan with deciduous broadleaf forest region were the densest regions in NPAs distribution, where there were various types of natural protected areas. 3) 70% of the study areas couldd reached an NPA within 2 hours, showing the NPAs had high traffic accessibility. The areas with good accessibility were mainly concentrated in the southeast and central regions, while the accessibility of the north and northwest regions was relatively poor. These indicate that regions where the NPAs were concentrated were also the regions with relatively fair economic development, and were in urgent need of integration of NPAs and optimization of territorial space.
