水电科技, 2023 农田水利关系着我国农业的未来发展，同时也关系到农村居民的经济水平，然而农田水利工程管理，却面临前所未有的挑战，自然环境成为制约农田水利工程的障碍，农田水利年久失修，基础设施得不到补充，现代化技术无法形成网络覆盖，现代化设施无法支援到位，同时政府管理缺失也是农田水利工程所面临的另一个难题，因此在农田水利工程管理上必须拿出相应的对策。

Estimation of spatiotemporal trends in bat abundance from mortality data collected at wind turbines
Conservation Biology, Volume 35, Issue 1, Page 227-238, February 2021., 2021 Abstract Renewable energy sources, such as wind energy, are essential tools for reducing the causes of climate change, but wind turbines can pose a collision risk for bats. To date, the population‐level effects of wind‐related mortality have been estimated for only 1 bat species. To estimate temporal trends in bat abundance, we considered wind turbines

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1807-1820, May 2026.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

Wildlife Letters, Volume 3, Issue 3, Page 109-117, September 2025.We found that the Asian Openbill primarily roosted near waterbodies and frequently used farmland habitats, with significantly higher populations observed during the breeding season. Farmland and wetland areas exhibited a positive effect on the species' habitat use.

Servicesheds connect people to the landscapes upon which they depend
People and Nature, Volume 7, Issue 1, Page 112-126, January 2025.Abstract Ecosystem services (ES) are benefits people receive from nature. To sustain these benefits, we need to spatially connect communities benefitting from specific ES with landscape features that generate the ES. A variety of process‐based models support ES assessments by estimating the biophysical supply of ES that comes from landscapes.
