This paper analyses the classification and characters of wetland resources in Chongqing .It also explores the problems of the utilization of wetland resources and puts forward some countermeasures.At present,the wetland area of Chongqing is 1 402.16×10 3hm 2,accounting for 17% of total land area of Chongqing,among which there are 1 222.53×10 3hm 2 of artificial wetlands and 179.63×10 3hm 2 of natural wetlands,accounting for 87.19% and 12.81% of the total wetland area respectively.The wetland distibutes widely but not equally in Chongqing and has abundant biodiversity.The present exploitation of wetland resources is not reasonable.The area of natural wetland gradually decreases;the ecological function of wetlands declines;the pollution in wetland is severe;the biodiversity of wetland reduces.In order to protect and exploit rationally the wetland resources in Chongqing,some countermeasures are put forward,such as investigating,sorting and appraising the present situation of wetland resources,and carrying out utilization programming.Preventing wetland pollution,establishing protection network,setting up managemant mechanism,and strengthening lawmaking,publicity and education on wetland resources.

就重庆市湿地资源的分类和特点以及利用中存在的问题进行分析 ,并针对性地提出相应的对策。重庆现有湿地面积 140 2 .16× 10 3 hm2 ,占全市土地面积约 17%。其特点是人工湿地面积大 (占湿地总面积的 87.19% ) ,分布广但不平衡 ,生物多样性丰富。目前的开发利用不尽合理 ,造成天然湿地面积减少 ,功能下降 ,污染严重 ,生物多样性降低等问题。为了保护重庆的湿地资源并加以合理利用 ,必须查清湿地资源现状并进行分类评价 ,在此基础上进行湿地资源利用规划 ,治理湿地污染 ,建立湿地保护网络 ,建立湿地管理机制 ,加强湿地立法工作以及宣传和教育工作。

The Shapotou National Nature Reserve, situated on the southeastern edge of the Tenggeli Des-ert, is a nature reserve for desert and semi-desert eco-systems. Animal species and their abundances inthe reserve were investigated during 1986 - 1987. In order to know the growth and decline of animal re-source in the reserve since 1986, we investigated animal species, their amount and environmental condi-tions during 1998 - 1999. Nineteen protected animal were recorded in 1998 - 1999, among which threespecies are class Ⅰprotected species and the others belong to class Ⅱ protected species. In comparisonwith 1986 - 1987, the species protected by law in China increased by seven species. Thirty-five addition-al species of birds were recorded, among which eleven species were new records for Ningxia. Three addi-tional species of mammals were recorded, but three species of rodent were not re-encountered in the sec-ond survey. Two species of amphibian and reptiles also were not re-encountered. Comparing animal a-bundances between 1986 - 1987 and 1998 - 1999, bird numbers in wetland habitat increased significant-ly, but those in village farmland, desert and sand-stabilization forest decreased. Specifically, the amountof bird as environmental indicator, such as Athene noctua, Passer ammodendri, Passer montanus, Caleri-da cristata, Cuculus canorus, and Streptopelia orientalis, were significantly reduced. Not only did rodentspecies richness decrease, but numbers also declined markedly. The main factors which led to the growthand decline of animal species and their amount in Shapotou National Nature Reserve were: (1) the de-struction of sand-stabilization forest ruined through economic action of human beings and plant diseases;(2 ) falling groundwater level, serious wetland pollution and the addition of abundant nutrients to water;(3 ) degradation of meadow and grassland; (4) enlargement of the area of farms and ponds.

1986-1987年首次全面调查了宁夏沙坡头自然保护区的动物种类及其数量。为了解1986年以来保护区动物资源的消长变化及其原因,1998-1999年又4次调查了该地脊椎动物种类及数量。10多年来沙坡头自然保护区的动物资源变化明显。 1999年国家重点保护动物比 1986年增加 7种,已达 19种,其中国家Ⅰ类保护种类 3种,Ⅱ类保护种类 16种。鸟类增加 35种,其中宁夏新记录11种;兽类新增 3种;两栖类和爬行类各减少 2种;鼠类减少 3种。1999年与1986年相比,湿地景观水鸟种类和数量显著增加,村庄农田景观、荒漠景观和固沙林景观鸟类种类和数量减少。环境指示种类纵纹腹小■(Athene noctua)、黑顶麻雀(Passer ammodendri)、树麻雀(Passer montanus)、凤头百灵(Calerida cristata)、大杜鹃(Cuculus canorus)、山斑鸠(Streptopelia orientalis)等种群数量明显减少。鼠类不但种类减少,数量也明显下降。影响动物种类、数量发生变化的主要因素是由于病虫害、人类对土地开发利用和生产活动引起的防风固沙林面积减少;地下水...

There are different types of wetlands on the China coast. Wetland ecological system is week. Wetland resources have obviously decreased because of unreasoning reclamations of wetland, excessive exploitation of resources, strictness of wetland pollution and damage of coast balance state. The damage of wetland induced the decrease of capability of natural disaster, effect of carbon conservation and environment purification. We should establish an integrated, standardized and scientific system for the protection and management of wetland, which enables the restoration of regressive wetland, furthest exerts the functions and benefits of wetland ecological system, and guarantees sustainable utilization of national wetland resources.

湿地具有特殊的生态特点、功能和效益。湿地生态系统是脆弱的,盲目的开垦、污染的加剧和海岸均衡状态的破坏,使湿地资源明显减少。湿地的破坏,导致防御自然灾害的能力降低,净化环境的作用降低,固存碳源的作用剧减。中国沿海有多种类型的湿地,应该进行地质调查和研究,建立完善、科学、规范的湿地保护和管理体系,使退化的湿地得以恢复和治理,最大限度地发挥其功能和效益,保证湿地资源的可持续利用。
