树木多，保绿人员人均1000棵以上，平时的修剪及不定期侧枝整形工作量大

There are many trees, and the per capita number of green keepers is more than 1,000. The usual pruning and irregular lateral branch shaping work is heavy; the pest is heavy. To prevent and control thorn moths, white moths, longhorn beetles and other pests, the annual drug consumption and spraying tasks are heavy , Maintenance difficulties: Severe pests and diseases lead to hollow trees, and heavy windy weather often breaks branches, which increases the workload of cleaning staff; large trees have luxuriant leaves that affect daylighting, and the tree species is single, aging, and too disordered; turf damage and degradation: serious greening settings It is too old and can not meet the needs of today's roadway and parking space renovation. <br>(2) Public supporting facilities (community roads) are aging and difficult to maintain. The <br>rainwater outlets are unevenly distributed, the drainage pipes are not unblocked, and road water accumulation and rainwater inversion are prone to occur in heavy rains; gas systems (such as gas valves) are placed on sidewalks, The roadway or green space not only does not meet the current design specifications, but also brings inconvenience to the passing pedestrians and vehicles. There are serious problems in the heating system. The original heating pipeline uses warm trenches to arrange the heating pipelines. The pipelines are severely corroded and have poor thermal insulation capabilities. The path does not meet the current design standards; the road lighting system has serious problems, the number of street lights is small, the distribution is uneven, and the cable aging is serious. The night illuminance of the entire community is far from meeting the normal lighting requirements of the residents of the community. The method of connecting the nearby power supply during the maintenance process Also caused more street lights control points

More trees, green per capita more than 1000 trees, usually pruning and irregular side branch shaping workload, heavy pests, for the control of hedgehogs, American white storks, cattle and other pests, the annual drug use and dosing tasks are very heavy, maintenance difficulties: serious pests and diseases lead to trees hollow, windy weather often blow off branches, to the cleaning staff increased workload; The degradation of turf damage is serious: the greening setting is too old and cannot meet the needs of the current road and parking change.<br>(2) Public facilities (community roads) aging, maintenance difficult.<br>The distribution of rainwater mouths is uneven, drainage pipes are not smooth, heavy rain and rain are prone to road water accumulation, rainwater irrigation phenomenon, gas system (such as gas valves) placed on sidewalks, road ways or green space, not only does not meet the current design norms, but also to passers-by vehicles inconvenience; Uneven distribution and cable aging is more serious, the whole district's night illumination is far from meeting the normal lighting requirements of residents of the community, the maintenance process of near-power supply practices also caused more street lamp control points.

There are many trees with more than 1000 green keeping personnel per capita. The workload of pruning and irregular side branch pruning is heavy. In order to prevent and control the insect pests such as the thorn moth, the American white moth and the longicorn beetle, the annual dosage of drugs and the work task of spraying are very heavy, and the maintenance is difficult: serious diseases and insect pests lead to hollow trees, and the branches are often blown off in windy weather, which increases the workload of cleaning personnel; large trees At the same time, the tree species is single, aging and too disordered; the turf is seriously damaged and degraded; the greening setting form is too old and can not meet the needs of today's roadway and parking space reconstruction.<br>(2) Public facilities (community roads) are aging and difficult to maintain<br>The distribution of rainwater outlets is uneven, and the drainage pipeline is not smooth. In case of heavy rain and rainstorm, it is easy to cause road ponding and rainwater pouring back; the gas system (such as gas valve) is placed on the sidewalk, roadway or green space, which not only does not conform to the current design specifications, but also brings inconvenience to the passing pedestrians and vehicles; there are serious problems in the heating system, and the original heating pipeline adopts warm ditch to arrange heating pipeline Serious corrosion and poor insulation capacity, pipeline diameter does not meet the current design standards; road lighting system problems are serious, the number of street lamps is small, uneven distribution and cable aging is serious, the nighttime illumination of the whole community is far from meeting the normal lighting requirements of residents in the community, and the practice of connecting power supply nearby in the maintenance process also causes more street lamp control points
