摘要 根据国家第7次森林清查资料和林业统计年鉴等权威数据,利用基尼系数法和空间统计法分析我国林地产出水平的省际差异及空间关联模式。结果表明:各省区林地面积与林业产值均显著不同,林地产出水平差异较大,总体上处于高度不均衡状态,导致林地产出水平省际失衡的关键因子主要是西部缺林省份及沿海多林省份;各省区林地产出水平总体呈现出较强的空间集聚趋势,局部为“低一低”型关联模式的省区在中西部地域上呈现连片分布态势,沿海省市多处于“高一高”型关联状态。 This article based on the authoritative data form 7th National Forest Inventory material and Forestry Statistical Yearbook, using the Gini coefficient and spatial statistics method, analyses inter-provincial differences and spatial association patterns of woodland output levels in China. The results indicate that there is a significant difference among woodland area and forestry output of various provinces, especially, the output level of woodland is in a highly non-equilibrium state as a whole. Western lack-woodland provinces and coastal multi- woodland provinces lead to inter-provincial the imbalances; woodland output level of various provinces shows a strong overall trend of spatial concentration. In part, the provinces under the model of "low-low" association are in mid-west region, they present contiguous geographical distribution, but the provinces under the model of "high-high" association are in the eastern region.
