Threats to and management of Natura 2000 protected areas relative to agricultural practices
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

Design and Implementation of Resident Population Information Management System for a Township [PDF]
, 2015 随着我国科技水平的不断发展，对于人口信息的统计工作也需要与时代接轨，改变原有仅展示一些统计数据的传统统计方式。借助地理信息系统的直观展示特点，将数据与表现形式相结合，能够做到人口信息在社区甚至楼宇的直观显示，方便查看和信息显示。通过这种友好的用户界面的设计和实现能够满足当前我国政府以及相关的统计部门对于人口信息统计工作的要求。 论文的主要研究内容有： 首先，本文基于GIS技术、B/S三层架构、UML建模技术、软件工程开发模型以及微软SQLServer2012数据库设计并实现了人口综合信息管理系统。 其次，

Integrative Conservation, Volume 5, Issue 1, Page 115-124, March 2026.We found the estimated use of tiger bone glue within the last 12 months to be 6.9%. We found a stated motivation of taking TBG to improve health, and by the suggestion of one's social group. We suggest reducing the acceptability of TBG as medicine and encouraging non‐animal‐based medicinal alternatives.

Design and Implementation of Online Environmental Monitoring System Based on B/S [PDF]
, 2015 随着社会经济的快速发展和人类生活水平的逐步改善，人类在创造所需物质文明的同时，环境污染和生态破坏也在日益加重。传统的环境监测系统缺乏长时间的、具有代表性的监测数据，无法适应长期有效管理机制的需求，所以需要一种远程的在线环境监测系统。随着计算机网络技术的快速发展，建立一套自动化的环境在线自动监测系统，是环境监测发展的一个必然趋势。它能及时反映环境质量，实时跟踪污染源的变化，能准确预测各种突发环境事件。 针对传统监测方法的缺陷，本文基于B/S架构进行在线环境监测，利用GIS、ArcGISServer ...
