| 中文摘要:西藏巴宜区降水量丰富，但地质灾害频发，森林生态系统的水源涵养功能取决于森林景观空间结构的优劣，这对于区域生态稳定至关重要。以西藏巴宜区为研究区，基于复杂网络理论和景观生态学分析方法识别并构建区域森林景观空间网络，并运用复杂网络特征指标及鲁棒性分析方法分析该森林景观空间网络的拓扑结构特征及抗破坏能力。结果表明：西藏巴宜区的森林景观空间网络度分布呈现幂律分布，具有无标度性特征，该网络具有非均匀特性，网络结构稳定性较差，且随机攻击下的边与节点恢复鲁棒性优于恶意攻击下的恢复鲁棒性。 |

| Abstract:The Bayi District of Tibet is rich in rainfall and frequent geological disasters. The water conservation function of the forest ecosystem is vital to regional ecological stability. The stable performance of its functions depends on the spatial structure of the forest landscape. Therefore, the forest landscape should be studied accurately. The characteristics of the spatial structure are of great significance to the subsequent optimization of the layout. Taking Bayi District of Tibet as the research area, based on complex network theory and landscape ecology analysis methods, the forest ecological corridor was extracted through the least cumulative resistance model, and then the fragile ecological nodes on the forest ecological corridor were identified. It constituted a forest ecological network intertwined with “point-line-surface”. And the complex network static characteristic index and robustness analysis method were used to analyze the topological structure characteristics and anti-destructive ability of the forest landscape spatial network. The results showed that the degree distribution of the forest landscape spatial network in Bayi District of Tibet presented a power-law distribution and had the characteristics of non-scaling. The network had non-uniform characteristics, the network structure was less stable, and under random attacks, the edge and node recovery robustness was better than malicious attacks. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
