The United Nations Sustainability Development Goals call for additional tree cover in cities in order to provide needed environmental,economic,and social ecosystem services.We inventoried tree cover and potential tree cover with i-Tree Canopy across the metropolitan area of 10 megacities,in 5 continents and biomes.We estimated the value of tree cover to reductions in air pollution,stormwater,building energy,and carbon emissions,by developing biophysical scaling equations with i-Tree Eco benefit estimates.

为在直接序列扩频-最小频移键控(DS-MSK)数字化接收机中设计和实现抗干扰模块,分析了存在干扰条件下DS-MSK信号的最小均方误差(MMSE)最优滤波问题,考虑到最优滤波难于直接实现,讨论了用自适应抗干扰滤波(AAJF)来逼近MMSE最优滤波性能.对非线性滤波加以改进,提出了部分解扩非线性滤波(PDNF).蒙特卡罗仿真表明:PDNF滤波性能明显优于传统非线性滤波,接近MMSE最优滤波性能.
体系结构建设是加强信息系统建设的基本前提,是实现我军信息化建设的重要手段,更是解决当前我军在信息系统建设方面存在的互联、互通、互操作性差等问题的重要措施.对此,文章总结了美军体系结构框架的演进过程,从十个方面系统剖析了美军体系结构框架成功构建的发展策略,旨在为我军体系结构建设提供借鉴.
分析了一种压电型先导阀的结构及工作原理，建立了先导阀的数学模型。在此基础上，利用AMESim仿真软件对先导阀进行了PWM控制仿真研宄，分析其静、动态特性；并运用压力反馈、PlD控制等复合控制方法，仿真表明叫该方法能有效提高阀的性能．大大降低稳态误差。

Ecosystem services in urban areas are regarded as multiple environmental benefits fostered by urban-rural landscapes.A wide range of ecosystem services have been largely affected by land use and cover
There are plenty of researches on the relationship between urban development and its environmental effects.Some research found the U-shape,N-shape Environmental Kuznets Curve when it comes to the rela
As cities represents the microcosms of global environmental change,it is very important for the global sustainable development by decoupling environmental pressure from economic growth on city level.I
Over the past 50 years,humans have changed ecosystems more rapidly and extensively than in any comparable period in human history.The main causes are to be found in the ever-increasing demands for res
As a scarce strategic resource,energy is essential for national and regional socio-economic development.The supply security of energy resources is of big importance especially in cities,the main consu
With a continuously growing share of the worlds overall energy consumption,the transport sector has been acknowledged as one of the most important contributors to global carbon emissions.From two time
