Modelling past and future land‐use changes from mining, agriculture, industry and biodiversity in a rapidly developing Southeast Asian region 采矿、农业、工业和生物多样性保护影响下东南亚快速发展区域过去和未来土地利用变化模拟

open access: yesIntegrative Conservation, Volume 2, Issue 1, Page 43-61, March 2023., 2023
We apply an integrative perspective to modelling current and future land‐use change in Kuantan, Malaysia, a location with highly biodiverse forests, and also a hotspot of land‐use change. The region is representative of the types of development challenges faced by countries in Southeast Asia, which are also biodiversity hotspots.

Early incisor lesions and Equine Odontoclastic Tooth Resorption and Hypercementosis: Reliability of radiographic findings

open access: yesEquine Veterinary Journal, Volume 55, Issue 2, Page 261-269, March 2023., 2023
Summary Background In clinical practice, early diagnosis of Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) and other resorptive incisor diseases is difficult to achieve. The radiographic appearance of subtle pathological changes has not been described in detail and might be confused with age‐related changes.

Evaluating the role of time in range as a glycemic target during short‐term intensive insulin therapy in patients with newly diagnosed type 2 diabetes 在新诊断的2型糖尿病患者中评估短期胰岛素强化治疗期间血糖达标时间作为血糖目标的作用

open access: yesJournal of Diabetes, Volume 15, Issue 2, Page 133-144, February 2023., 2023
Highlights Whether time in range (TIR) during short‐term intensive insulin therapy (SIIT) was associated with treatment response to the therapy in patients with newly diagnosed type 2 diabetes was uncertain. TIRPIR, which was calculated according to the percentage of glucose points within predefined glycemic targets, was superior to TIR3.9–7.8mmol/L ...

景观格局与土壤养分流动

open access: yesShuitu Baochi Xuebao, 2000
不同尺度上景观格局与生态过程的关系是景观生态学的研究重点。根据Habit-Food-Resource范式,研究土壤养分流动与景观格局之间关系可为认识不同尺度上景观格局与生态过程的关系提供帮助。土壤侵蚀是山区和丘陵地区影响景观格局和土壤养分流动的重要过程之一。景观格局间土壤养分动态变化还没有引起足够的重视。采用SCS范式,评价了黄土高原地区景观格局与土壤养分流动的关系。

水土保持措施驱动村域土地利用景观格局变化——以米脂县高西沟村为例

open access: yesShuitu Baochi Xuebao, 2023
以陕北地区典型乡村——榆林市米脂县高西沟村为例,探究其在水土保持措施下土地利用景观格局变化及驱动因素,对黄土丘陵区水土保持、景观格局优化、美丽乡村建设和生态可持续发展具有指导意义。基于高西沟1986年、2004年、2022年遥感影像,借助ArcGIS、ERDAS和FRAGSTATS等软件,运用动态度、转移矩阵、景观格局指数对土地利用变化进行分析,并对其驱动因素展开探讨。结果表明:(1)林地和草地是高西沟的主导地类,约占区域总面积的80%,耕地、未利用地呈减少趋势,水域和建设用地无较大变化 ...

Relative Habitat Suitability of the Gray Fox (Urocyon cinereoargenteus) in the Central Great Plains 大平原中部灰狐 (Urocyon cinereoargenteus) 的生境相对适宜性

open access: yesWildlife Letters, EarlyView.
Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

黄河黑山峡水电开发建设对区域景观格局的影响

open access: yesShuitu Baochi Xuebao, 2006
应用景观生态学原理,建立了区域景观格局指标体系;以黄河黑山峡水电开发建设方案为背景,在3S技术支持下,通过对TM影像解译,在获取大量数据和分析项目区景观格局现状的基础上,研究了水电开发备选建设方案对区域景观格局的影响。结果显示,备选方案中的梯级方案实施后,区域景观的多样性、均匀度以及景观生态风险指数变化不大,对区域原有景观生态系统的影响相对较小,区域原有生态体系的性质和功能没有发生显著变化。
