常见园林的照明方式有哪些?

答案

参考答案:

(1)一般照明指不考虑局部的特殊需要,为整个被照场所而设置的照明。这种照明方式的一次投资少,照度均匀。

(2)局部照明指对景区(点)某一局部的照明。当局部地点需要高照度并对照度方向有要求时,宜采用局部照明,但在整个景区(点)不应只设局部照明而无一般照明。

(3)混合照明由一般照明和局部照明共同注册的照明。在需要较高照度并对照射方向有特殊要求的场合宜采用混合照明。此时,一般照明照度按不低于混合照明总照度5%~10%选取,且最低不低于20lx

Kids and Ponds

Years ago there was a group of kids who would hang around at some local ponds in the woods near their houses in Warwick, Rhode Island. In summer they caught frogs and fish. When winter arrived they couldn’t wait to go skating. Time passed, and the ponds became the only open space for the kids to enjoy themselves in that neighborhood.

One day. a thirteen-year-old boy from this group of kids read in the local newspaper that a developer wanted to fill in the ponds and build over a hundred small houses called condominiums. So the boy went door to door and gathered more than two hundred signatures (签名)to stop the development A group of citizens met and decided to support him.

At the meeting of the town planning board (委员会),the boy was quite nervous at first and spoke very softly. But when he saw the faces of his friends and neighbors in the crowd and thought about what was happening to their favorite ponds,his voice grew louder. He told the town officials that they should speak for the citizens. He also insisted that they should leave enough space for children. A few days later,the developer stopped his plan.

Nine years later, when that teen was a senior in college, he was informed that the developer was back with his proposal to build condominiums. Now twenty-two years old, he was studying wetlands ecology. He again appeared before the town planning board. This time as an expert witness, he used environmental protection laws to explain restrictions on development in and around wetlands and the knowledge of wetlands ecology to help improve the development. Finally some condominiums were built, but less than half the number the developer wanted. The ponds where those kids used to hang around were protected by a strip of natural land,and are still there today.
