Current assessments of protection effectiveness are mostly based on comparisons through a time series or between the inside and outside of protected areas without taking space neighborhood and spatial heterogeneity effects into consideration. In order to identify the protected area's management effects in the context of climate change and human uses, this study took the Sichuan Zoige Wetland National Nature Reserve as the study area and used the “BACI” experimental design principle to develop an evaluation framework to assess the protection effectiveness. Patch density, largest patch index, and contagion index were used as indicators to measure the space neighborhood effects and the protection effectiveness. The results showed that: 1) the wetland area in Zoige Wetland National Nature Reserve has shrunk and the sandy area has been reduced. On the contrary, area of shrubland, grassland and constructed lands has increased; 2) There existed leakage space neighborhood effects in the past 40 years. 3) The Zoige wetland has kept on fragmenting, but the reduction rate of the wetland patch area inside the nature reserve has slowed down. The decrease in connectivity between patches has also been mitigated. Management measures have alleviated landscape fragmentation within its territory. We suggest that in order to eliminate the emerging island effect, human activity both inside the reserve and in adjacent areas should be controlled.
