王金亮导师研究小组论文在SCIE一区Top期刊JAG上发表

2021年6月8日，以云南省高校资源与环境遥感重点实验室2020级博士研究生李杰为第一作者、王金亮教授为通讯作者撰写题为“Dynamic changes of vegetation coverage in China-Myanmar economic corridor over the past 20 years”的论文在SCIE期刊International Journal of Applied Earth Observation and Geoinformation（JAG）（SCIE一区，2019年IF: 4.650，Top期刊（ 2020年12月最新基础版）线上发表了（https://authors.elsevier.com/sd/article/S0303-2434(21)00085-4；https://doi.org/10.1016/j.jag.2021.102378）。让我们恭喜李杰！热烈祝贺团队取得好成绩！

中缅经济走廊是“一带一路”倡议的旗舰项目，2020年从概念规划到实际建设取得重大突破，随着而来的建设活动将对当地植被产生不可避免地影响。该论文通过3S空间技术和多种统计学模型的交叉，定量分析了2000-2019年中缅经济走廊植被覆盖度的时空变化，并预测未来可能趋势。具体来说：（1）分析植被覆盖的时间变化，包括长期趋势、周期性变化和转折点检测；(2）量化植被覆盖度的空间变化，包括空间格局、趋势和波动特征；(3）预测未来植被覆盖变化趋势，包括持续性和可能的趋势。研究结果可为区内植被有效保护、走廊建设合理布局等提供科学支撑。

该论文得到了王金亮教授主持的国家重点研发计划政府间国际科技创新合作重点专项：用地理空间技术监测和评估土地利用/土地覆被变化对区域生态安全的影响（2018YFE0184300），云南省青年学术技术带头人（2008PY056），云南省高校高原山地资源环境遥感监测与评估科技创新团队（IRTSTYN）的资助。

摘要：The China-Myanmar Economic Corridor (CMEC) is a flagship project of the "Belt and Road" Initiative (BRI), which have made a major breakthrough from conceptual planning to actual construction in 2020, and subsequent construction activities will have a definite impact on local vegetation. To provide scientific support for vegetation conservation and sustainable development of the CMEC, statistical methods such as Morlet wavelet analysis, Mann-Kendall mutation test, Sen's slope estimator, Mann-Kendall trend test, and coefficient of variation were adopted to analyze the spatio-temporal changes in vegetation coverage; Hurst analysis was adopted to further predicted likely future development trends. The results suggested that: (1) The CMEC experienced an overall increasing Fractional Vegetation Cover (FVC) at a rate of 0.21%/yr from 2000 to 2019; 2005 was the mutation year when FVC changed from a slow increase to a significant increase. The FVC changes was mainly controlled by a 12-month oscillation period. The seasonal average FVC increase was slightly different, which were ranked in descending order, as winter (0.29%) > autumn (0.17%) > summer (0.14%) = spring (0.14%). The increasing trend in autumn and winter exceeded those in spring and summer, particularly after 2018. (2) The area with an increasing trend in FVC was five times of those with a decreasing trend (~49.40% VS ~9.97%). The former was mainly clustered in the Dehong Dai and Jingpo, China, central and southern part of sub-region Myanmar; whereas the latter primarily distributed in main urban zones such as Mangshi, Ruili, Mandalay, and Yangon. Above areas where FVC changes significantly were affected by human activities such as afforestation, agriculture and construction, and the fluctuation of FVC changes was strong in the short term. (3) Future changes in FVC indicated that ~88.08% of the CMEC will show a stable and positive trend, mainly agglomerated in forest and farmland zones. However, it is expected that vegetation coverage in main urban zones and several unused land zones formed by farmland degradation will experience further decrease, and the conservation of vegetation in these regions should be a focus during the construction of the CMEC.
