土地利用和土地覆盖变化是全球生物多样性危机的主要原因，保护区对于防止栖息地丧失至关重要。体制和社会经济条件的迅速变化，如1991年前苏联的解体，往往会引发大范围的LULCC。我们的目标是绘制1984年至2010年森林覆盖率和农业用地的变化图，以评估俄罗斯欧洲温带地区两个严格保护区--奥尔奇斯基和莫尔多夫斯基国家自然保护区的有效性。我们分析了三个陆地卫星足迹的陆地卫星图像的密集时间序列，并应用支持向量机分类和基于概率的变化检测来映射森林干扰。然后，我们使用匹配统计来量化保护区的有效性。我们的分析突出了俄罗斯欧洲部分相当大的后苏联LULCC。土地利用、土地利用变化和气候变化的地图显示，干扰占森林总面积的5.02%，在后苏联时代干扰率大幅下降。我们还发现，1988年使用的农业用地中有39.89%在1991年后被遗弃，导致广泛的森林再生。与周边地区相比，Oksky和Mordovsky国家自然保护区的森林干扰概率显著降低（低0.1%至-3.5%）。这表明，保护区是相对有效的限制在欧洲俄罗斯人为引起的森林干扰，尽管控制水平较低，自然保护的基础设施受到侵蚀。此外，我们发现这些保护区周围的土地覆盖发生了剧烈变化，特别是森林再生，突出了保护机会。在土地利用、土地利用的变化和土地利用的变化迅速增加的时期，保护区可在生物多样性养护方面发挥关键作用，遥感加上相应的统计数据为监测养护工作的成败提供了重要工具。(c)2013 Elsevier Inc.

Land-use and land-cover change (LULCC) is the main cause of the global biodiversity crisis and protected areas are critical to prevent habitat loss. Rapid changes in institutional and socio-economic conditions, such as the collapse of the former Soviet Union in 1991, often trigger widespread LULCC Yet, it is unclear how effective protected areas are in safeguarding habitat within them during such periods of rapid LULCC. Our goal here was to map changes in forest cover and agricultural lands from 1984 to 2010 in order to assess the effectiveness of two strictly protected areas, Olcsky and Mordovsky State Nature Reserves, in temperate European Russia. We analyzed dense time series of Landsat images for three Landsat footprints and applied a support vector machine classification and trajectory-based change detection to map forest disturbance. We then used matching statistics to quantify the effectiveness of the protected areas. Our analyses highlighted considerable post-Soviet LULCC in European Russia. The LULCC maps revealed disturbances on 5.02% of the total forest area, with strongly declining disturbance rates in post-Soviet times. We also found that 39.89% of the agricultural land used in 1988 was abandoned after 1991, leading to widespread forest regrowth. Oksky and Mordovsky State Nature Reserves had a significantly lower probability of forest disturbance (-0.1 to -3.5% lower) in comparison to their surrounding areas. This suggests that protected areas were relatively effective in limiting human-induced forest disturbance in European Russia, despite lower levels of control and an eroding infrastructure for nature protection. Moreover, we found drastic land-cover changes, particularly forest regrowth, in the surroundings of these protected areas, highlighting conservation opportunities. Protected areas can play a key role in biodiversity conservation during periods of rapid LULCC, and remote sensing coupled with matching statistics provide important tools for monitoring the success and failure of conservation efforts.
