近年来,我国森林面积逐年扩大,这也就使得我国森林的防火工作面临了更多的挑战。在森林防火工作当中,风力灭火器的使用十分广泛,也成为扑灭森林火灾的最常用和最有效地工具。但是
经过数十年的考古发掘,人们对中国史前最大城邑之一的良渚古城的结构及城外环境有了比较准确的判断。这座存在于距今4 300~5 300年前的古城具有完整的支撑农业生产和古城生活的水利系统。那时的良渚人在古城西部及北部的山间和山脚地带兴建了一系列堤坝,用以削减山体的季节性洪峰并储水利用。蓄水湖泊又与古城的环城河和城内河道等水系和设施共同构建了维护城市安全运转的水调节系统,这项水利工程既是良渚人能够安居并持续繁衍的基本保障,也使得良渚成为一座名副其实的山水之城,不知道那时的良渚人是否能够欣赏城外优美的湖光山色风景
森林植被可以有效调节全球气候,因此林业在近年引起了各方的关注。然而想要加强林业的生产建设,首先需要做好对其的全方位调查以及合理地设计规划,以此达到维护全球生态系统平衡
