in 2011, Ji'nan began to promote the roof greening, giving the implementation unit subsidies per square meter to 80 to 100 yuan. However, a reporter found that the roof greening promotion difficulties, weight bearing and waterproof limit the majority of the roof subsidy is difficult to offset the cost, later maintenance by the property rights units. And roof greening is mainly in the organs and units, difficult to enter residential areas. These lead to the slow promotion of the roof greening in the provincial capital.
the existing rooftop greening is very few, mainly the organization unit
in the noon of July 29th, Lin Yukai, deputy director of the Jiefang Road office in the Ji'nan calendar, is busy in the office of the two building.
on the two floor, about 200 square meters of bulge, planting roses, privet and so on. There are also small pavilions and stools, and the stone path covered with grass runs through the roof. Walking in it is like a garden.
there was a lot of dust on the top of the floor before the wind was dusty and dared not to open the window. Now, on the contrary, the green plants outside the window covered the dust and cleaned the air, especially from March to September. Talking about the advantages of greening roofs, Lin Yu opens up, and greenery reduces room temperature by two or three degrees in summer.
two floor green plants are mainly managed by the street greening section. The cost is not very high, mainly watering, and also a typical example of Lixia District. Lin Yukai introduced it.
however, Mr. Wang said that there are not many units with such maintenance professionals and various conditions. The section of the social greening section of the landscape Bureau of the calendar under the calendar told reporters in 2011 to start a pilot project. There are now 19 units in the region to realize the roof greening, with an area of about 25600 square meters.
the unit has already realized the roof greening, such as the original hospital, the security room of the Shandong agricultural department, the calendar building, the Yanshan office, the Wen Dong Office and so on. Most of them are organs and units, and few residents apply for them. Song chief said.
roof is difficult to load, residents do not support, in community promotion is difficult
most of the roof design is waterproof, not considering the weight bearing factors, the roof greening needs to design waterproof layer, water leaking layer, soil, grass, and many roofs are difficult to bear the weight. Lixia District Garden Bureau staff introduction, and need to take into account the waterproof factors, so roof greening is difficult to stay in the residential area.
according to the plan, the new roof of Yanshan should be afforested on the roof. The roof greening of Yanshan's new residence has been stopped for a long time. Last year, the preparations for the new roof may have ended because of technical and human reasons. Mr. Zhang, a resident of the residential area, said that when the building was built, the roof was full of muddy water, rather than built, so that it could walk to the roof. This idea is very good, but now manpower and material resources can not be reached.
resident Mr. Luan told reporters that because they do not live on the roof, the roof greening does not affect themselves, and the top floor residents will not be willing, because once the water is leaking, only the top residents will bear. Residents in the residential area do not understand the roof greening, nor do they catch cold.
the three floor of No. 5 building in Wenhua garden is about 500 square meters of green, rose, holly, turf, and rich rose, together with wooden corridors, really let a bright eye. On the top of the building, the environment is very good, but the soil is thin, they often come to water, here the property fee is 1.95 yuan per square meter, the good environment is also exchanged for high property fees. Mr. Tian, who is on the top of the floor, said.
Wenhua Garden property cleaning and greening Department Manager Cheng Feng told reporters that few other areas have a roof greening, Wenhua Garden property has a special greening personnel, daily inspection, normally, water four or five times a week. Watering, artificial, fertilizing, spraying and so on add up to between 1000-1500 yuan per month. According to this calculation, the top floor green plants cost more than 24 yuan per square meter per year. And these expenses are paid by the units themselves.
according to the regulations, the greening of the roofs of the district has no right to apply, only the property and Industry Committee will apply, but the property will not cut its own meat and take out funds to do this.
