17、 of the n ature sig nifica ntly.綠色植物有吸收有害氣體，釋放新鮮空氣的功能，同時還具有減弱噪聲、防火防災、殺菌等功能, 因此我國在城市總體規(guī)劃時把城市中工廠的綠化提高到非常重要的地位。Green plants can absorb harmful gas and release fresh air. At the same time, they candecrease no ise, preve nt fire and sterilize as well. So the Ian dscape for the in dustrylocated in the cit

19、 in the desig n of Ian dscap ing layout, there is a collectively large area of gree n landalong the internal road of the in dustrial park and in the south of the site. Lan dscapeoods entrance of the Food R&D centre.desig n in this project adopts frutex, flowers and gree nsward. Evergree n frutex

20、 will be pla nted on both sides of the road and so are the gree nsward and flowers. Lan dscap ingratio reaches 20.1% of the gross site area, which could represe nts the moder n factorystyle with very n ice Ian dscap ing廠區(qū)四周設置圍墻，沿圍墻設置綠化帶，如此可以防止外界空氣對工廠的污染，降低噪聲。廠內(nèi)道路兩側盡可能加強綠化，不但可以凈化空氣，同時還能起到改善廠貌的效果。Ther

21、e are fen ces and gree nbelts around the land plot. They can help to preve nt thepollution from outer atmosphere and decrease the noise.

23、Food R&D centre is the same as that of the existi ng factory.8 交通組織 Transportation本次新建工程利用原有廠區(qū)內(nèi)部道路出入口，交通順暢。The n ewly-built Food R&D centre uses entran ces of the existi ng roads of the pla nt andwhich are smoothly for tran sportati on本次新建工程采用現(xiàn)有道路已經(jīng)能夠滿足交通、消防要求，未增加新道路。原有道路為一環(huán)型混 凝土道路，道路最小寬度為7.

24、5m。這一環(huán)型道路系統(tǒng)充分滿足了廠區(qū)內(nèi)部交通要求，同時也滿足了消防環(huán)路的要求。The newly-builtFood R&D centre adopting the existing road has already meets therequirements of transportationand fire fighting,so no new road is added. The existingroad is a ring like concrete road and the minimumwidth is 7.5m. The circular road system has
