观光农业园区道路系统规划研究

近年农业观光园的发展如雨后春笋,但其规划标准尚属空白,如道路作为主要规划内容之一,规划者只能凭经验和感觉进行,由此导致了一些问题.本文参考现行的相关规范,结合农业观光园的具体特点,以重庆铜梁县生态荷花园为案例,采用布局优化法对园区道路进行规划.结果表明:规划的主干路长度为3 024.7m,密度为1.77km/hm2,次干路长度为5 214.6m,密度为3.04km/hm2,人行游步道长度为9 244.7m,密度为5.40km/hm2,道路面积率为2.7%,考虑景区内水体占有一定比例,均在合理范围内.运用布局优化法规划得到的生态荷花园区路网规划图与园区原有路网相比,其布局情况大体相同,这也验证了布局优化法进行园区道路网规划的科学性、合理性和可实施性.园区路网规划设计方法的建立不仅为园区道路规划提供了理论依据,更为园区道路规划提供科学合理的规划方法.

On Planning Standards of Sightseeing Agriculture Park Road System

Agricultural sightseeing gardens have mushroomed in recent years ,but its planning standards are still blank .For instance ,roads ,as one of the main content of the planning ,have not been programmed in a scientific way by planners ,who can but deal with them with experience and impulse .Thus ,it has caused some problems .This article refer to the current related specification and combination with the fea-ture of agricultural sightseeing gardens ,with the examples of the ecological lotus garden layout of Tongli-ang County ,Chongqing Municipality ,optimization method has been used to park road planning .The re-sults show that the length of the trunk road planning is 3 024 .7 m ,density is 1 .77 km/hm2 ,secondary road length of 5 214 .6 m ,density is 3 .04 km/hm2 ,pedestrian tour trail length is 9 244 .7 m ,density is 5 . 40 km/hm2 ,road area ratio of 2 .7% ,consider scenic water bodies within a certain proportion ,all within a reasonable range .By applying the method of layout optimization planning of ecological lotus park road net-work compared to the original network ,its layout is the same ,which also verifies the layout optimization method of park road network planning is scientific ,reasonable and practical .The establishment of the park road network planning and design method can provide theoretical basis not only for the park road planning , but also for park road planning to provide scientific and reasonable planning methods .
