摘要
竹资源广泛分布于热带、亚热带和温带地区,是许多不可再生资源的良好替代品,其生长迅速、分布范围广的特点在减缓气候变化和发展中国家脱贫减困等方面发挥着重要作用。遥感技术广泛应用于资源监测、森林结构定量化反演,具有监测范围广、时空精度高的优点。系统梳理遥感各类数据源在竹资源监测中的应用、竹资源时空动态变化监测及竹资源监测分类方法。重点总结监测制图的数据源与分类方法,并对各类方法的精度进行统计分析。提出竹资源遥感监测要注重使用多源遥感数据和分类方法探索,加强特殊竹种、竹特定生长阶段和竹数量与质量监测为未来研究重点,以期为濒危野生动物保护、贫困地区脱贫、竹产业开发利用、发展中国家民生改善等提供技术支撑。
Bamboo resources are widely distributed in tropical,subtropical and temperate regions.They are good substitutes for many non-renewable resources.Their rapid growth and wide distribution play an important role in mitigating climate change and developing countries to lift poverty and reduce poverty.Remote sensing technology is widely used in resource monitoring and quantitative mapping of forest structures,and has the advantages of wide monitoring range and high precision in space and time.This paper systematically sorts out the application of remote sensing data sources in bamboo resource monitoring,the temporal and spatial dynamic change monitoring of bamboo resources and the bamboo resource monitoring and classification method.Focus on the data sources and classification methods of monitoring and mapping,and statistical analysis of the accuracy of various methods.It is proposed that the remote sensing monitoring of bamboo resources should pay attention to use the multi-source data and classification methods,strengthen the special growth stages of bamboo species and bamboo,and monitor the quantity and quality of bamboo as the future research focus,in order to protect the endangered wild animals,poverty alleviation in poverty-stricken areas,and bamboo industry.Provide technical support for development and utilization,improvement of people's livelihood in developing countries.
