| 中文摘要:以内蒙古荒漠绿洲区为研究区，将复杂网络与潜在生态网络进行类比分析，研究生态系统能量流动的特征，分析潜在生态网络的关联性、完整性和稳定性。结合相应生态因子，构建生态阻力面，提取潜在生态廊道1103条、生态节点992个。潜在生态网络度分布符合幂律分布，因此，可将赋权网络适配到潜在生态网络进行分析。结果表明，荒漠绿洲区潜在生态网络连通性较差，聚类特征不明显；生态节点分布较为分散且破碎，完整性偏低；潜在生态网络内部能量流动情况较为单一，不够稳定。荒漠绿洲区内生态景观破碎化，发展与生态保护的矛盾较为突出，整体生态环境亟待优化。 |

| Abstract:Taking the Inner Mongolia Desert Oasis as a research area, the analogy analysis of complex networks and potential ecological networks was carried out to study the characteristics of ecosystem energy flow and analyze the connectivity, integrity and stability of potential ecological networks. Combined with the corresponding ecological factors, the ecological resistance surface was constructed, and 1103 potential ecological corridors and 992 ecological nodes were extracted. The potential ecological network distribution was consistent with the power law distribution, so the weighted network can be adapted to the potential ecological network for analysis. The potential ecological network connectivity in the desert oasis area was poor, the clustering characteristics were not obvious; the ecological nodes were scattered and fragmented, and the integrity was low; the energy flow inside the potential ecological network was relatively simple and not stable enough. The ecological landscape in the desert oasis area was fragmented, and the contradiction between development and ecological protection was more prominent. The overall ecological environment needed to be optimized. |
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.
