Green Corridor Planning And Control In Luotian

The object of this research is about the green corridors of Luotian. This reach is Survey seventeen urban roads to research the situation of the green corridors. And utilize the suitability analysis and the minimum distance method to build the green corridors of Luotian. The results are as follows:First, Analysis of green road corridor(1) In Luotian, the average of the green corridor connectivity is0.52. Wanmizhai Avenue connectivity up to0.78.And other roads’connectivity is low, only0.33. As Yishui South Road, Silk Road, Dabieshan Avenue and Yingbin Avenue.(2) In Luotian, the main trunk road corridor density is4.9km/km2, which is more than the national standard. And minor arterial corridor density is3.9km/km2, which is meet The National Standards.(3) The curvature of the road corridor is close to1. And the form of the road section is too simple, primarily as a board of two belt and three boards of four belts. And the former is accounted for71%.(4) In the survey of17street plants in the road corridor. Arbor: magnolia, osmanthus, palm, camphor, ginkgo. The missy species:acer palmatum, crape myrtle, arborvitae, red maple, malus halliana. Shrub:photinia fraseri, tortoiseshell holly. Camphor and osmanthus are most widely And there is lack of shrub layer. So the road landscape is ineffective.Second, Analysis of the green river corridor(1) The Yishui River corridor landscape connectivity is0.67, density is0.79km/km2, and the connectivity is1.12/km.(2) The Yishui River corridor’s curvature is1.18, close to1. The justice river green corridor layout the form of straight.(3) The Yishui River is constructed with cement revetment. Both sides of the main landscape of residential areas and commercial land landscape and road landscape are three types.(4) There are different species in different sections of the Yishui River. Arbor: plane trees peels, magnolia, osmanthus. Shrubs including lobular privet, pittosporum, photinia fraseri, boxwood, rubrum. There is lack of herbs, so the road landscape is ineffective.Third, Construction of green corridor network system Green corridor system is divided into five levels:first corridor, second corridor, third corridor, the potential corridor and stepping-stone corridor.(1) First corridor: Wuying Highway. Width is more than200meters.(2) The second corridor: Protective green belts of river, and the protection green belt of high-pressure corridor. Width is between50meters to200meters.(3) The third corridor: Constitute with protection green space and green parks. Width is between15meters to50meters.(4) Potential corridor: Affiliated green space. Width is between5meters to10meters.(5) Foot stone:Constitute with small piece of green space, acontinuous corridor.Forth, design and optimization of typical green corridorsExtract three typical green road corridors in accordance with the division of the road corridor level and function type:Yishui River Road, Dabieshan Avenue and Fengcheng Avenue.
