The study history of cave invertebrate in China is summarized in this paper. We list new species of Chinese troglobiotic invertebrate found over the past twenty years, and two types of cave invertebrate are divided according to the differences of the habitat: terrestrial community and aquatic community. The review also emphasizes the current research on Arachnolida, Diplopoda, Insecta, Crustacea and Castropoda.

本文介绍了我国洞穴无脊椎动物研究的简史，列出了近20多年来我国发现的真洞穴无脊椎动物种类，并根据栖息环境的不同，将洞穴无脊椎动物划分为陆生群落和水生群落；着重介绍了蛛形纲、重足纲、昆虫纲、甲壳纲、腹足纲的研究现状。

This article that focuses on the systematic and in-depth research in the current primal problem about abnormal burst pressure reservoir depress burst pressure has procured following main fruits:1 It forms the method which could obtain massive vertical static state mechanics parameters.2 In a foundation of acquisition of rock mechanics parameters,apply bent lamella that as mechanical model along with characteristic of actual geologic characteristics to analysis curvature for anticlinal strcture, get homologous tectonic stress value throug relation between the curvature and stress and different principal curvature in anticlinal structure,consequently set up laminational stress model for anticline reservoir. The block lamination for existed fracturing date has formed method of setting up mechanical model of lamination terrestrial stress by abtaining the block tectonic stress coefficients which are got by complex utilization test, laboratory test and fracturing date playback.3 Analysesing the main reason which lead to high burst pressure by considering the characteristic of reservoir geology,reservoir,and rock mechanics and reservoir damage,etc.Establishing burst pressure quantitative prediction model which provide gist for depressing construction risk and optimizing construction craft under the condition of open hole completion ,gun-perforated completion and damaged reservoir.4 Provding theoretical basis for interpreting acidification pretreatment which could depress busrt pressure by finding the relation between the influencing factors and rock machanics parameters and analysing the factors that have effect on rock mechanics parameters. Expounding the mechanism of reaction of mixed monomineral and acid from the angle of microcosmic element, evaluating quantitatively acid sensilility of different kinds of mineral effectively, and determing the first-order reaction dynamical equation of each mineral.5 Revealing rock mechanics property chage as a result of acid flooding in different condition by sandstone traumata experiment in different temperatures which combined with rock mechanics triaxial stress experiment.6 Associating damage mechanics with sandstone acidizing, established sandstone damage mechanics model in the foundation of the recognition on the rock mechanics parametric variation which is caused by acid-rock reaction in both macroscopic view and microscopic view ,also demonstrated those processes and quantitative estimated the acid busrt pressure to direct the site operation.

Assuming that half of the carbon loss in the degraded terrestrial ecosystem in current forest and grass areas are restored during the next 50 years or so, the terrestrial ecosystem in China may sequestrate～12.0Pg of organic carbon from the atmosphere, which represents a considerable offset to the industry's CO〓 emission.

5在现有的气候条件下，未来50年或更长的时间上，如果我们能通过有效的土地利用措施使我国现有林地和草地面积上的生态系统碳损失量恢复其中的1/2，那么我国陆地生态系统将具有～12.0Pg C的碳汇潜力。
