According to the present situations of protected area in China and referring to the definition and category abroad, we suggested the forest natural protected area mainly include three types as follow: Nature Reserves (NR; types of forest eco-system), Forest Parks and Public Welfare Tree Farm. Researches of evaluation on ecotourism resources of forest natural protected area focused on two aspects basically: to appraise and account the ecotourism resources monetarily from the standpoint of pure economics; to assess the exploitability of ecotourism resources based on the theories of conservation biology and ecology, in which finding the reasonable equilibrating point between protection and: utilization was emphasized. On the studies of development pattern of forest ecotourism resources, it is necessary to deal with the relationship between protection and exploitation correctively, namely to put the protection as the first consideration and balance the "Tree r.1ajor Benefits" so that prompting the virtuous circle afforest ecotourism.

根据我国自然保护地的实际情况，参考国外自然保护地的定义与分类方式，可认为我国的森林自然保护地主要应主要包括森林生态系统类型自然保护区、森林公园及公益林场三种类型；森林自然保护地的生态旅游资源评价研究主要集中在两方面：一是单纯地从经济学角度对旅游资源游憩价值进行货币化评价与核算，二是从保护生物学和生态学角度对资源的可开发性进行评价，其侧重在于找到保护与开发的的科学平衡点；在森林自然保护地旅游资源的开发模式研究上，必须正确处理开发与保护的关系，把保护放在第一位，坚持"三大效益"兼顾的原则，才能实现森林生态旅游资源开发与保护的良性循环。

Temperature and relative humidity were monitored during daytimes.

从护岸区域小环境出发，以怀柔区怀九河作为研究对象，选择其一渡河段及四渡河段抛石＋植物、浆砌石＋大块石＋植物两种生态护岸作为监测对象，以生态护岸上近水边和护坡处游人休闲活动区域作为监测点，对监测点的温度和相对湿度进行实地监测。

Riprap stone+ plant ecological embankment and slurry stonelaying+ boulder+ plant ecological embankment were selected as research objective. Near river and on the revetment are the places that people regularly to visit and have a rest. Based on the situation, we select them as monitoring points on the two ecological embankment of Huaijiu River. Temperature and relative humidity were monitored during daytimes.

By application of the technology concerning organizing or reconstructing the submerged plants to decontaminate or recover water quality is an effective measure of ecological engineering.

利用组建或重建沉水植物技术净化水质或进行水体生态修复是一种有效的生态工程措施。

In the ancient Book of Poetry , we have these lines: Reed and rush are dark and green;/ As hoarfrost the white dew is seen.

生态城区，即一种融合于自然之中的生态化居住方式。

It is regarded as a useful indictor for measuring ecological pressure imposed by human being and a most powerful indictor of regional sustainability.

做为一种偏重生态的可持续评估手段，生态足迹方法往往难以全面地反映区域可持续发展能力。

The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation, temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data.

用涡度相关法对亚热带红壤丘陵区人工针叶林的二氧化碳、水、热通量进行了观测，重点分析了23m、39m两层高度的观测结果，同时把观测期分为春季和冬季两个不同时间段作了对比：结果表明，不管冬季还是春季，39m高度所测的总通量值和夜间通量值都要小于23m的观测值，这种通量差别表明：23m高度的观测结果更接近当地生态系统与大气之间的通量交换值，在此种生态类型条件下用涡度相关法测碳通量时，在23m、39m两层高度之间仍然存在大气平流现象；该试验区植被在冬季仍然可以进行光合作用，而且光合作用所吸收的CO2大于呼吸作用所排放的CO2，因此该种生态系统在冬季仍表现为碳汇；春季的碳通量值为冬季的2倍以上。

The others are Mucuna sempervirens,Parthenocissus trcuspidata,Wistaria sinensis Sweet in turn.According to the distinction of ecological functional of these four plants,the kind of plants which should be chosen under various ecological environment conditions or for different demands of ecological function of the plants were given.1. The most suitable plants for the area which get serious pollution such as factory,roadway and so on is Mucuna sempervirens.the other plant which more suitable is Rosa banksiae Ait.2. The most suitable plants for the hospital and the area for the children and the old is Mucuna sempervirens. And we can also select Parthenocissus trcuspidata.3. In the green area of modern enterprise that produce precision instrument,Rosa banksiae Ait is the best selection.4. Rosa banksiae Ait is the most suitable plants in resident green area. Planting Mixed with Mucuna sempervirens has better effectiveness.

以四种植物的生态功能性差异评价为依据，提出不同生态环境条件下和对植物不同的生态功能性要求的垂直绿化应选择的植物： 1 在道路、工厂等污染较严重的地区搞垂直绿化，最合适的植物是油麻藤，其次可选择木香； 2 医院及儿童、老人活动区的垂直绿化首选是油麻藤，其次是爬山虎； 3 生产精密仪器的现代企业绿地，垂直绿化植物选择以木香为首选，可结合大面积的爬山虎墙面绿化； 4 居住区绿地的垂直绿化植物选择以木香最符合要求，再以油麻藤进行混植，效果较好。

The production of Feeding Bacillus Microbiological- Candy Peptide Element is a kind of additive with high-quality , high-efficient , and without public nuisance. It is consist of some active substance as feeding bacillus and so on, and it is refined by the technology of contemporary cell, gene and the regulation of zymolysis.

The dissertation modifies the model of Holdridge's indexes of lifezone according to the features of the ecological climate of Xinjiang. The influence of the variation of vegetation caused by the climate variation of Xinjiang in recent decades is also analyzed. In recent 40 years, the type of life zone hasn't changed, the area and number of patch changed only. The diversity changed but not too much..That is, diversity of life zone changed in little range, the whole entiroment is still be a rather stable state, whill be goo for desertation expand contrandictorily.

根据新疆生态气候特征和生物地理规律对Holdridge生命地带分类模型进行修正，分析新疆近几十年来气候变化所引起的植被变化对于新疆土地荒漠化的影响。40多年来，新疆生命地带的类型数量并没有产生变化，只是各类型的面积和斑块数的变化，多样性有所波动，但是波动不大，也就是说生命地带多样性的震荡幅度不大，整个生态环境处于一种相对稳定的状态，这种稳定的生态环境状态有利于荒漠化的逆向发展； 7。
