千岛湖为"抗州-黄山-南京-无锡-苏州-上海"黄金旅游线上的一颗明珠,1998年国内外游客达130余万人次,旅游收入3.21亿元.千岛湖虽然具有丰富的旅游资源和优越的旅游环境,但由于树种比较单一,林相缺乏层次和季相变化,影响景观质量,且病虫害呈逐渐迈延之势,因此必须进行林种树种结构调整以适应旅游业发展的需要,内容包括大规模造景、中规模造景、小规模造景、营造濒危珍稀树种异地保存林、岛屿消落带覆盖林、近水草药带、四季观花林、针阔混交林与观叶观果林、生态经济林等. 相似文献

Forest Fertilization: Some Guiding Concepts 总被引:5,自引:0,他引:5
Drawing on results from studies of nutrient cycling and fertilizerresponse in pine, three concepts are proposed: (1) Fertilizersare generally of benefit to the trees, not the site, and measureablepermanent site improvement is only likely if the amount of nutrientapplied is large in relation to the soil capital. (2) In theabsence of any site improvement, fertilizer response is bestexplained, and costed, by using the simple analogy of an accelerationthrough time, leading to a reduction in rotation length. (3)Consideration of the variations with tree age in the patternsof nutrient uptake, cycling and immobilization, and in the captureand retention of atmospheric nutrients, leads to the suggestionof three distinct nutritional stages. During the years priorto canopy closure (Stage I) tree growth is very dependent onsoil nutrient concentrations and response to a number of nutrientscan be expected. Thereafter, (Stage II) responses are unlikelyunless foliage biomass has to be reconstructed, e.g after thinningHowever, on low nitrogen capital sites, immobilization of nitrogenin biomass and humuus as trees age can lead to the progressivedevelopment of deficiency (Stage III), a deficiency that mayeventually disappear as tree demands fall with age. It is suggested that together these three concepts provide arational framework that will aid in the explanation and extrapolationof results from empirical fertilizer trials 相似文献

This paper compares and contrasts the ways in which forest recreationis handled in Western Europe and some tentative suggestionsare made of what we could learn from one another. The demandfor forest recreation has been rising rapidly everywhere andthe rise is likely to continue, but perhaps at a slower ratethan before. One of the major contrasts between countries concerns the lawsof public access to forests. Britain is one of the few countrieswhere access is neither enshrined in law nor tolerated everywhereby custom, although it is granted voluntarily to virtually allpublicly owned forests and also to some privately owned ones. Where access is granted, the emphasis throughout Western Europeis to encourage the peaceful enjoyment of nature rather thannoisy leisure pursuits which can be equally well catered forelsewhere. The main problems are associated with litter and the damagecaused by excessive deer populations which are favoured by huntingand environmental interests. With regard to litter, the bestsolution is to keep recreational facilities absolutely cleanand tidy at all times because fewer people set a bad examplethan follow one. No satisfactory solution to the game problemhas yet been found. In most of Western Europe less effort has been made than inBritain to quantify the costs and benefits of recreation forwhich no charges are made; this reflects a fundamental differenceof attitudes to the valuation in money terms of some of thegood things in life. Finally, the paper advocates the opening of more forests inBritain to the general public. 相似文献
