Mitigation of Legacy Effects in Invaded Soil via Alien Plant‐Derived Biochar 题目:外来植物生物炭对其入侵后土壤遗留效应的修复作用

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 686-694, December 2025.
The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

Governing the Ungovernable: Mapping the Development of Groundwater Irrigation and Groundwater Policies in India

open access: yesWorld Water Policy, Volume 11, Issue 4, Page 1048-1064, November 2025.
ABSTRACT Groundwater governance is complex due to several externalities associated with groundwater being an invisible natural resource tied to the land with millions of extractors and limited means of exclusion. The paper traces the evolution of groundwater irrigation in India and the corresponding change in groundwater laws and policies to address ...

生态系统服务价值在土地利用规划中的应用

open access: yesShuitu Baochi Xuebao, 2006
生态系统服务价值在理论、评价尺度、核算方法等方面的研究取得了很大的进展,但其结果的应用方面研究较少,以河北省易县为例,将生态系统服务价值应用到土地利用规划的生态效益定量研究中,这对维持生态平衡,采取合理的土地利用方式,建立可持续的土地利用模式具有指导意义。依据易县1997年、2001年和2010年的3期土地利用规划数据,估算了土地利用规划所引起的易县及其28个乡镇的生态系统服务价值的变化。结果表明,易县的生态系统服务价值从1997年的16.87×108元增加到2010年的20.06×108元,增加值为3.

Ecological Restoration of Rubber Monocultures: Strategies for Biodiversity and Ecosystem Recovery in Tropical Regions 题目:如何将橡胶林恢复为多样森林?

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 345-353, September 2025.
Restoration of monoculture in protected and marginal areas can be organized into two phases (1) identification and prioritization of restoration sites based on remote sensing or field survey then assessing degradation level, and (2) implementation of appropriate restoration interventions.

耕作方式和氮肥用量对旱地小麦产量、水分利用效率和种植效益的影响

open access: yesShuitu Baochi Xuebao, 2021
为探索旱地小麦增产增效增收协同的耕作方式及其配套施氮技术。2016—2017(欠水年)和2017—2018(丰水年)年度,在豫西典型旱区洛宁县设置夏闲期深松(ST,麦收后2周左右隔年进行)和翻耕(PT,传统的7月或底8月初连年进行)2种耕作方式为主区,设置4个氮肥用量为副区(播前基施纯氮0(N0),120(N120),180(N180),240(N240) kg/hm2)的田间定位试验,分析了土壤水分以及小麦产量、水分利用效率和种植效益。结果表明:与翻耕相比,深松提高了休闲效率,播前、开花期和成熟期0 ...

Reoccurrence of Dust Storms in South Asia and Their Implications for Vegetation Health 南亚沙尘暴的再次出现及其对植被健康的影响

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.
Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Effects of Shifting Cultivation on the Western Hoolock Gibbon (Hoolock hoolock) in Western Myanmar 刀耕火种对缅甸西部西部白眉长臂猿 (Hoolock hoolock) 的影响摘要

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 503-513, September 2025.
Fire occurrence increased with proximity to roads and villages, indicating that human access and activity are major drivers of fire risk. We analyzed spatial patterns of fire in relation to human settlements. Our findings highlight the need for fire management strategies that consider accessibility and human presence in conservation planning.

Land use performance evaluation based on attribute weight optimization algorithm and analysis of land use performance differentiation(基于属性权重优化算法的土地利用绩效评价及差异分解分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2019
为了解土地利用绩效现状,探究区域间绩效的差异特征,以31 个省域2011—2015 年的数据为研究对象,从土地利用结构、经济社会效益和生态可持续性3 个角度构建绩效评价指标体系,用综合主客观赋权的属性权重优化算法确定指标权重,运用改进的TOPSIS 模型测度绩效值,并用泰尔指数组间分解法定量分析区域内和区域间差异对总绩效差异的贡献度。结果表明:按三大地带分组时,东部差异对总体差异贡献最大,西部次之,中部最小;按六大常规分类分组时,华北、华东地区对总体差异贡献较大,东北、西北地区贡献较小 ...

Patriotic rabbits or toxic men? Media ideology, entextualization, and enregisterment on Chinese interfaces

open access: yesJournal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.
Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...
