项目摘要
Geographers and other environmental scientists are interested in understanding the spatial patterns associated with changes in the diversity of forest trees, including spatial variations due to differing tree species distributions. Changes in spatial variation often can be associated with different habitats at multiple scales, giving insights on how forested landscapes are organized. The humid forests of the western Amazon are some of the most biodiverse tropical forests in the world but are poorly known because of their inaccessibility. An increased understanding of floristic patterns and their associations with habitat type, especially in remote areas such as these forests, not only contributes to scientific research but also makes it possible to facilitate biodiversity conservation. A traditional time-consuming, labor-intensive field survey of vegetation itself can no longer suffice for the needs of documenting vegetation in large areas in order to conduct regional-scale conservation projects in diverse tropical forests. The objectives of this doctoral dissertation research project are to use data from tree inventories, remote sensing, and conservation assessments to examine the similarities among the spatial distributions of trees and the forest diversity patterns as measured at a fine, local scale with the spatial distributions detectable at a coarser, regional scale, and to take a multi-scale approach in terms of data acquisition and analysis to produce scale-dependent conservation recommendations for indigenous territories in a part of the Ecuadorian Amazon. As such, this project will contribute to several different intellectual disciplines, including biogeography, tropical ecology, and biodiversity conservation. It also will allow for evaluation of the effect of scale on pattern and process. At the local scale, the doctoral candidate will use high-resolution satellite imagery, such as Quickbird, to examine patterns of forest structure and diversity, thus combining spatial analysis of the distribution of tree communities at ground level (with tree inventory plots) and from above (through remote sensing). She will spatially and conceptually combine multiple scales of satellite imagery from sensors like Quickbird and Landsat TM/ETM for predicting forest stand characteristics and tree diversity patterns among different vegetation and habitat types at a regional scale. The study region is located in a biodiverse part of the western Amazon. Standardized 1-ha tree inventory plots will be established to document the forest stand composition.This project is expected to provide fundamental baseline knowledge about vegetation and tree diversity patterns, facilitating understanding of forest biogeography in remote areas with great biodiversity. It has considerable applicability in implementing regional systematic conservation planning, which is a great need in tropical environments. The project is expected to help initiate integrative conservation implementation in the western Amazon. By using multi-scale remote sensing vegetation analysis to identify areas with great tree and habitat diversity, this study will provide an efficient, cost-effective method to locate the areas that still retain abundant environmental and biological diversity. By integrating other data layers that contain other factors influencing strategies for conservation implementation, such as climate, topography, and social aspects, this study will identify and target conservation prioritization zones using multiple criteria. The study area covers the Achuar, Shiwiar, and Zapara indigenous territories in the southeastern Ecuadorian Amazon where no previous tree inventory, remote sensing analysis, or conservation implementation has been conducted. Research results will be disseminated to the indigenous communities for their feedback and evaluation, thereby enabling the needs and opinions of the indigenous people to help attain balance between sustainable natural resource management and biodiversity conservation in a highly species-rich but fragile ecosystem. As a Doctoral Dissertation Research Improvement award, this award also will provide support to enable a promising student to establish a strong independent research career.
地理学家和其他环境科学家感兴趣的是了解与森林树木多样性变化相关的空间格局,包括不同树种分布造成的空间差异。空间变化的变化往往与不同尺度上的不同生境有关,从而使人们能够深入了解森林景观是如何组织的。亚马逊西部的潮湿森林是世界上生物多样性最丰富的热带森林之一,但由于难以接近而鲜为人知。增加对植物区系格局及其与生境类型的关系的了解,特别是在这些森林等偏远地区,不仅有助于科学研究,而且使促进生物多样性保护成为可能。传统的耗时、劳动密集型的植被实地调查本身已经不能满足记录大范围植被的需要,以便在不同的热带森林中开展区域规模的保护项目。这一博士论文研究项目的目标是利用树木清查、遥感和保护评估的数据,检查在精细的局部尺度上测量的树木的空间分布和森林多样性格局之间的相似性,以及在较粗的区域尺度上可检测到的空间分布之间的相似性,并在数据获取和分析方面采取多尺度方法,为厄瓜多尔亚马逊地区的一部分土著领土提出依赖尺度的保护建议。因此,这个项目将对几个不同的学科做出贡献,包括生物地理学、热带生态学和生物多样性保护。它还将允许评估规模对图案和工艺的影响。在地方尺度上,博士生将使用高分辨率卫星图像,如Quickbird,检查森林结构和多样性的模式,从而结合对树木群落在地面(与树木清查地块)和自上而下(通过遥感)分布的空间分析。她将在空间和概念上结合来自Quickbird和Landsat TM/ETM等传感器的多个尺度的卫星图像,以预测区域尺度上不同植被和栖息地类型之间的森林林分特征和树木多样性格局。该研究区域位于亚马逊西部生物多样性的一部分。将建立标准化的1公顷树木调查地块,以记录森林林分组成。该项目预计将提供有关植被和树木多样性格局的基本基线知识,促进了解生物多样性丰富的偏远地区的森林生物地理学。它在实施区域系统保护规划方面具有相当大的适用性,这是热带环境的迫切需要。该项目预计将有助于启动亚马逊西部地区的综合保护实施。通过使用多尺度遥感植被分析来识别树木和栖息地多样性丰富的地区,这项研究将提供一种高效、经济有效的方法来定位仍然保留丰富环境和生物多样性的地区。通过整合包含影响保护实施战略的其他因素的其他数据层,如气候、地形和社会方面,这项研究将使用多种标准确定和确定保护优先区。研究区域包括厄瓜多尔亚马逊东南部的Achuar、Shiwiar和Zpara土著领地,这些地区以前没有进行过树木清查、遥感分析或保护实施。研究结果将分发给土著社区,供他们反馈和评估,从而使土著人民的需要和意见能够帮助在高度物种丰富但脆弱的生态系统中实现可持续自然资源管理和生物多样性养护之间的平衡。作为博士论文研究改进奖,该奖项还将提供支持,使有前途的学生建立一个强大的独立研究生涯。
