Abstract: Designing a suitable zoning scheme for forest land protection can play active role in guiding and regulating the sustainable usage of forest resources, the balance of ecology and the coordinated development of economic and ecological civilization. This paper takes the spatial distribution properties of forest land into account when formulating a scientific protection scheme of forest land, taking the Tunchang County locating in Hainan Province as an example. Firstly, the quality of forest land was evaluated scientifically, and the local spatial autocorrelation analysis was introduced to explore the spatial characteristics of forest land quality. Then, the natural and socio-economic properties of forest land are combined with the spatial distribution characteristics to form the basis for protection zoning of forest land. Results indicate that: 1) the quality value of forest land varies from 5.40 to 8.56 in the whole county with little variation, overall being in moderate and upper levels. In detail, 13.71% of the forest land is the first-grade land which mainly locates in the southwestern Xichang Town and along the border between Nankun and Fengmu Town, while 18.35% of the forest land is the fourth-grade which mostly spreads over Poxin and Nanlü Town. The second-grade and third-grade forest land take 32.57% and 35.26% respectively which disperse all over the county. 2) The index of Moran's I is 0.531 7, which means strong positive spatial autocorrelation of forest land quality. Therefore, it reveals that the forest land quality has a certain spatial clustering characteristics in the county. 3) According to the local spatial autocorrelation analysis, the protection scheme of forest land in Tunchang County was designed. It is consistent with the quality evaluation results basically, which divides the forest land into key protected region, active protected region and general protected region. Different protection measures can be implied in different kinds of protected regions. In conclusion, taking the spatial distribution property of forest land into consideration in the design of protection zoning is a method for forest land protection division, and it provides a new idea for rational forest land use planning.
