      Living in a green area can make you live longer, according to research published today.The research

also shows  that the  difference in  life expectancy (预期寿命) between rich and poor becomes

smalleramong those who live in an environment with parks and trees.

     Richard Mitchell, from Glasgow University, and his colleagues, found that the gap between the

number of deaths of people on high incomes and the number of deaths of those on low incomes in green

areas was half that compared with figures relating to builtup areas.

     Green spaces, classified by the researchers as "open, undeveloped land with natural vegetation",

encouraged people to walk and be more active.Exercise in these settings could have greater benefits than

exercise elsewhere, the researchers said.

     The benefits potentially go beyond exercise.Studies have shown that being around green spaces can

reduce blood pressure and stress levels, and possibly help patients recover faster.

     A number of researchers have looked at the effects of greenery on our wellbeing.But few studies had

looked at whether living in green areas reduced health inequalities, the Glasgow team said.

     Using information from a landuse database of 2001, the researchers divided the preretirement

population of England into four groups according to income level, and five groups according to access to

green space.They then looked at death rate for 2001～2005.

     They found that the inequality in death rate from all causes relating to lack of money was less in those

populations in the greenest areas compared with the figures for people living in more builtup places.They

found an even stronger relationship when it came to deaths from certain diseases such as heart conditions

and stroke (中风). There was no difference, however, in deaths from lung cancer.

      The researchers said that changing the physical environment was an easier way to fight against poor

health than using media campaigns or giving out information on health."The result of the study is clear:

Environments that promote good health might be very important in the fight to reduce health inequalities."

江海市朝阳镇花园社区劳动保障服务站积极开发和采集就业岗位，帮助就业困难人员就业。他们最常用的办法之一就是和辖区用人单位建立就业联盟，在主动为单位开展一系列有针对性的就业服务的时间的同时，积极推荐辖区就业困难人员填补用人单位的岗位空缺。

在协理员小汪的帮助下，李大姐和王大姐都很快找到了满意的工作。就业联盟的建立使得花园社区劳动保障服务站推荐就业的效果明显提高。去年年底，经有关部门评估，花园荣获“省级充分就业社区”称号。
