From the perspective of forest resources change, this article uses comparative analysis and panel data regression to study the woodland use efficiency including forest resources quantity and quality change. The results show that although the forest coverage and forest stock volume per hectare show an overall upward trend, there are different change laws between the two; there are also differences in the influencing factors between forest coverage and forest stock volume per hectare (population density, rainfall and project having significant effect on forest coverage; population density, economic density and institution having significant effect on forest stock per hectare). Finally the recommendations are put forth for improving the woodland resources use efficiency: it is necessary to improve both the forest quantity and forest quality, focus on demand and supply, and pay equal attention to project promotion and property rights system reform.
