The lines with different color in the map represent different kinds of roads: the black lines are sealed roads while the brown ones are unsealed roads; the green lines are unformed roads and the blue ones are unknown roads. Also, different ranges of quandong site suitability in the map are indicated in different color too. The color from white to dark blue respectively represent the value of “0” to “1”.
The areas with the value of “0.9-1” show in dark blue in the map, which are the most suitable for growing quandong. While, the white areas represent the value of “0”. They are not suitable for planting quandong at all.
