Risks of concealing environmental degradation
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Assessing and strengthening community‐based coastal governance
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries

四川大学学报. 自然科学版, 2015 在线性近似下,Helmholtz方程能够描述小尺度大气声波波动.因此分析小规模大气声波波动特性,必须对Helmholtz方程进行求解.大多数求解Helmholtz方程的方法是在某些边界条件和初始条件下进行的,而边界条件和初始条件本身就是在假设、近似的基础上得到的,且会使得计算过程复杂和计算量变大.指数函数法具有多个自由参数是求解非线性问题精确解的一种十分有效、直接的工具,且在求解时不要考虑边界条件和初始条件,对函数进行指数和双曲正切变换的共同作用可近似为线性变换.基于上述思想 ...
