      Greenspace facilities (设施) are contributing to an important degree to the quality of the city

environment. Fortunately it is no longer necessary that every lecture or every book about this subject

has to start with the proof of this idea. At present it is generally accepted, although more as a self-proved

statement than on the base of a closely reasoned scientific proof. Recognizing the importance of

greenspaces in the city environment is a first step on the right way, this does not mean, however, that

enough details are known about the functions of greenspace in towns and about the way in which people

are using these spaces. As to this subject I shall within the scope (范围) of this lecture, enter into one

aspect only, namely the recreative function of greenspace facilities.  

     The theoretical separation of living, working, traffic and recreation which for many years has been

used in town and country planning, has in my opinion resulted in more attention for forms of recreation

far from home, while there was relatively little attention for improvement of recreative possibilities in the

direct neighborhood of the home. We have come to the conclusion that this is not right, because an

important part of the time which we do not pass in sleeping or working, is used for activities at and

around home. So it is obvious that recreation in the open air has to begin at the street door of the house.

The city environment has to offer as many recreation activities as possible, and the design of these has to

be such that more required activities can also have recreative aspect.  

     The very best standard of living is nothing if it is not possible to take a pleasant walk in the district, if

the children cannot be allowed to play in the streets because the risks of traffic are too great, if during

shopping you can nowhere find a spot for enjoying for a moment the nice weather, in short, if you only

feel yourself at home after the street door of your house is closed after you.
