Vertical pendulum(VP) tiltmeter is a kind of earthquake precursor observation equipment,which is used to record the interaction force associated with astronomical tidal tilts caused. Currently, VP broadband tiltmeter and vertical sensor(VS) vertical pendulum tiltmeter are primarily used. In this paper, we compare the two different instruments by using four aspectsdmechanical structure, circuitry, zeroing, and bandwidthdbased on their working principles and applications. We conclude that VP broadband tiltmeter is more superior compared with VS vertical pendulum tiltmeter because of its higher bandwidth and degree of automation.

为了给当地的生态用地保护和区域间生态补偿提供科学依据,该研究在坝上高原地区1990、1995、2000、2005、2010和2015年6期土地利用解译数据的基础上,通过GIS等工具分析了研究区域1990-2015年间生态用地格局演变的基本特征,并对生态用地的生态系统服务价值进行了计算。主要结论如下:1990-2015年期间,研究区域生态用地数量呈减少趋势,其中林地和其他生态用地数量在增加,草地和湿地数量在减少。生态用地活跃程度在2000-2015年比1990-2000年期间更高。林地的空间稳定性最好,然后为草地和湿地,其他生态用地稳定性最差。生态用地生态系统服务价值由46.01亿元上升到428.26亿元,增加了8.31倍,林地和湿地提供的生态系统服务价值最大,其次为草地,其他生态用地最小,应当继续加强生态防护林建设,采取生物恢复技术,人工补水,科学禁牧、休牧、轮牧,调整产业结构等措施恢复和增加林地、湿地和草地的生态系统服务功能。
