Efficiency of the current protected areas considering the projected distributions of all three taxonomic groups.

The taxonomic groups were considered together and separately using the Minimum set and Maximum coverage scenarios for both the 1961–90 and 2080–99 time periods. Minimum set values are a ratio between PRION output values for costs for the quasi-optimal solution and the current PA. Maximum coverage values are a ratio between the PRION output values for the targets of the quasi-optimal solution and the current PA. Efficiency is measured as the ratio between the existing PA’s and quasi-optimal solutions found by the software. The closer to 1 the values are, the more efficient the current PA’s are, as compared to the quasi-optimal solution found by the software.

本研究针对1961—1990年与2080—2099年两个时段，分别采用最小集（Minimum set）与最大覆盖（Maximum coverage）情景，对分类群进行合并与单独分析。最小集值为准最优解的成本对应的PRION输出值与当前保护地（Protected Area, PA）的PRION输出值之比；最大覆盖值为准最优解的目标对应的PRION输出值与当前保护地的PRION输出值之比。效率以现有保护地与该软件得到的准最优解之间的比值进行衡量。数值越接近1，说明相较于该软件得到的准最优解，当前保护地的效率越高。
