The impacts of tourism on the environment of Mussoorie, Garhwal Himalaya, India

Mussoorie, a hill resort in the Garhwal Himalaya reveals the changing trends and impacts of tourist activity on its environment. This study was carried out during 1993–1994 and it showed that while Mussoorie had a permanent residential population of 25400 during the winter months, in the peak tourist season of May and June the population exceeded 200000 per month. Because of this huge influx of tourists the demand for lodges/hotels and other related infra-structure and super-structure facilities and amenities in the area was enormous, and it imposed a great stress on the natural environment.The data collected showed that from 1958 to 1988 the number of tourists had increased gradually but that from 1989 tourism in the town escalated following the political disturbances in the Kashmir Valley. The main purpose of the tourism was recreation (80%). It was recorded that the greatest number (60%) of the tourists were middle aged, 53% of the tourists worked in professional services. The majority of the tourists preferred to use the indigenous hotels and about 96% of the tourists used a private vehicle rather than public transport.The installation of modern tourist related facilities and infra-structure has led to the aesthetic degradation of the landscape. Tourist facility development is often disorderly and scattered. To reduce the traffic to Mussoorie town it is suggested that some nearby places like Dhanolti and Park estate should be developed for tourism.     

城市“马路拉链”治理对策研究

城市\"马路拉链\"现象不仅带来了经济和环境损失,还诱发更深层次的社会和谐损失.该现象的产生源于错误的政绩观、城市地下管网管理体制弊端及针对\"马路拉链\"问题的监督和约束机制之不健全.为此提出三个治理对策:其一,摆正城市公共服务主客体基本立场,树立正确的政绩观;其二,从提高城市道路规划水平入手,对城市地下管网实施系统治理;其三,建立健全\"马路拉链\"监督与约束机制.

AQUATIC IMPACTS OF DEICING SALTS IN THE CENTRAL SIERRA NEVADA MOUNTAINS,CALIFORNIA1

ABSTRACT: The fate and effect of sodium chloride applied to Californian highways in the Lake Tahoe, Truckee River, and Yuba River watersheds were studied over a period of 14 months in 1974–75. Chloride levels in streams below major freeways were found to be elevated during the winter. The high chloride levels occurred after the application of salt to roads, decreasing as the time from application increases. Small lakes receiving runoff from major highways were also enriched with chloride. Several of these lakes displayed a temporary chemocline, which was sufficiently strong to stabilize a temperature inversion in one lake.     

一个研究街道峡谷流场及浓度场特征的三维数值模式

目前,研究街道峡谷内流场及机动车排放污染物的扩散行为特征所采用的主要方法为：采用野外测试法和物理模拟法,而采用三维数值模拟方法研究此问题的工作很少。本文创建了一个研究微尺度街道峡谷内流场及机动车排放污染物扩散特征的三维数值模式,即首次采用伪不定常方法,利用K——E闭合方案,建立了一个模拟城市街道峡谷内流场及污染物扩散特征与街道峡谷风场、街道几何结构及两侧建筑物高度对称性之间的复杂关系的三维数值模式。经过与实际监测资料及风洞实验对比,结果表明此三维模式具有较好的模拟精度,能够很好模拟峡谷内的风场及街谷几何结构对街道峡谷内流场及浓度场特征的影响,有很强的实用性。     

Analysis of Scavengers’ Activities and Recycling in Some Cities of Nigeria

The state of solid waste recycling by scavengers in Onitsha, a heavily commercial city in Anambra State, and some other urban areas such as Nsukka, Enugu, and Port Harcourt was analyzed. Data were obtained through interviews of scavengers who deal with recyclables. Although the activities of scavengers are sub-optimal, they can have a great impact on Nigerian economy with respect to resource conservation, creation of job opportunities, and reduction of the magnitude of waste disposal problems. A cost analysis is presented to compare the different forms of recycling utilized by municipal solid waste management. It is shown that a well-planned recycling program with recycling and composting would result in 18.6% savings in waste management costs and 57.7% in landfill avoidance costs. However, if the compost materials are not recycled, the corresponding savings in cost become 8.6% and 28.6%, respectively. The option with the lowest cost involves encouraging individual households to separate at the source their recyclables, which are bought by scavengers. This results in 78.0% savings in waste management cost and 79.5% landfill avoidance cost. A low-cost approach aimed at the integration of scavenging activities into conventional solid waste management is presented.

生态环境准入制度衔接成效、问题和优化建议

《中华人民共和国环境影响评价法》实施二十年以来,生态环境分区管控、规划环评、项目环评等制度共同筑牢了生态环境准入的防线,但也出现了管理边界不清晰、管理成效体现不足、制度联动机制保障不健全等问题,本文通过剖析典型规划中生态环境分区管控、规划环评、项目环评三项制度各自发挥的作用,调研部分地区管理实践,提出优化生态环境准入制度的对策建议：一是生态环境分区管控应发挥宏观引领和维护国家生态环境稳定的作用,与国民经济社会发展规划、生态环境保护规划等指导性规划同步研究、同期发布;二是规划环评应进一步筑牢“承上启下”的核心作用,上收部分规划环评的审查权限,提升规划环评文件质量,强化环评要求落实情况监督;三是项目环评应在生态环境准入制度体系中进一步优化简化,对环境影响可控、环保措施成熟的建设项目,可推动项目环评和排污许可两证合一,进一步强化建设主体的责任意识,通过制度整合发挥管理效能。

旅游活动对四川升钟水库水质的干扰度研究

运用TADI指数研究升钟水库的旅游活动对水体环境的影响,比较了旅游活动中各个环节对水体的影响程度,指数越大,对水质影响越大。结果表明：升钟水库景区旅游人均TN、TP污染物排放量分别为3.57g／d、0.59g／d,升钟水库景区7类旅游接待设施综合干扰指数排序为：住宿类渔家乐T1〉渔家乐餐厅T2〉酒店T3〉餐馆T4〉摊贩T4〉公厕T7〉博物馆T6,住宿类型渔家乐（T1）对水质干扰最大,属高度干扰型;博物馆（T6）对水质干扰最小,属低度干扰型。不同的食宿组合方式中,渔家乐住宿餐饮型的TADI指数最大,对水质的干扰最强,仅在餐馆就餐则TADI指数为最小,对水质干扰也最弱。     

Topographic Effects on Soil Organic Carbon in Louisiana Watersheds

Terrestrial carbon storage is influenced by a number of environmental factors, among which topographic and geomorphological features are of special significance. This study was designed to examine the relationships of soil organic carbon (SOC) density to various terrain parameters and watershed characteristics across Louisiana, USA. A polygon data set of 484 watersheds and 12 river drainage basins for Louisiana was used to form the landscape units. SOC densities were calculated for each soil map unit using the State Soil Geographic (STATSGO) database. Average drainage densities and average slopes at watershed and basin scales were quantified with the 1:24 K Digital Elevation Models (DEM) data, and the Louisiana hydrographic water features. Correlation and regression analyses were performed to determine relationships among drainage density, slope, elevation, and SOC. The study found an average watershed drainage density of 1.6 km/km² and an average watershed slope of 2.9 degrees in Louisiana. The results revealed that SOC density at both watershed and basin scales was closely related to drainage density, slope, and elevation. SOC density was positively correlated with watershed drainage density, but negatively correlated with watershed slope gradient and elevation. Regression models were developed for predicting SOC density at watershed and basin scales, obtaining regression coefficients (r ²) ranging from 0.43 to 0.83. The study showed that estimation of SOC at watershed and drainage basin scales combining DEM data can be a feasible approach to improve the understanding of the relationships among SOC, topographic, and geomorphological features.
