The achievement of this project can be briefly summed up as following:(1)the carbon contributing to karst processes mainly comes from ecological system itself under the condition of existence of vegetation and soil covers;(2)results indicates that the depositing processes of rainfall to CO2 is an important "sink" to global carbon cycle;(3)owing to the differences of vegetation and surface covering, the adjusting effect of ecosystem to environmental humidity, temperature and CO2 concentration near surface air which indicates different benefit of preventing water and soil from lose is marked;(4)the preponderant species of vegetation in the karst ecosystems which have different kinds of carbonate rocks are obviously variant, and this situation results to the clearly differences of the micro － habitat , structure of surface cover and water holding capacity;(5) the relevant study showed that the carpophagous animals and birds make a important role in the spreading of vegetation seeds. The designed experience for the study of seed reservoir was not able to obtain a satisfactory result.

主要研究成果包括：通过对表层系统碳库的研究，认为在有土壤和植被覆盖时，岩溶作用过程中的碳主要来自生态系统本身而不是母岩；降雨对大气碳具有重要&沉淀&作用，是碳的一个重要汇；不同植被类型表层岩溶系统对系统水份、空气湿度、气温、土温和近地表 CO2浓度等具有明显调节作用，具有不同的水土保持效益；不同母岩的岩溶生态系统的植被优势种、属差异明显，由此形成的小生境、地被物及其持水性差异巨大；对典型岩溶表层系统种子库的试验研究没有取得满意结果，但食果动物、鸟类对种子传播起到一定作用。

Its sensitivity has a great influence on the global climate system. The large-scale rough estimate with the remote sensing data will contribute to the global carbon storage, carbon cycle and the global balance changes. In this study, the NDVI data of the NOAA/AVHRR acquired on 1995 and 2000 were used besides the relevant ground weather data and the eradiate data.

本文计算了1995和2000年的我国陆地NPP，并在此基础上分析探讨了NPP的时间变化以及空间分布特征，并对森林、草原和农作物NPP的数量和时间变化特征进行了统计分析，对引起这种变化的主控因子进行了初步探讨，以增进对我国陆地生态系统NPP的时空格局变化及其控制因子的了解。

In a 1997 interview, Plass told me,"all sorts of things came together" that placed him at the scientific forefront: new detailed laboratory measurements of the absorption bands of water vapor, carbon dioxide and ozone; theoretical developments involving the influence of temperature and pressure on infrared absorption; new information about the carbon cycle and industrial emissions; and access to a new high-speed electronic computer to facilitate complex calculations of radiative transfer that replaced the older, graphical approximations.

在1997年的一次采访中，普拉斯告诉我：&所有的事情都赶在一块儿&，把他推到了研究的最前沿：测量水蒸气、二氧化碳和臭氧的吸收光谱带有了新的实验方法；温度和压强对红外吸收的影响理论有了新的发展；碳循环和工业废气排放有了新的资料；新的高速电子计算机代替了老式的图解近似法，让辐射传热的复杂计算变得简单了。

It is an indispensable aspect for confirming the content of carbon on earth, making clear karst dynamics system, and the global geochemistry process of carbon cycle, and the reasons of content of CO_2 increase in atmosphere, and the various cause of syndromic disaster in recently years.

深大断裂的深源CO_2释放作用研究是一项非常重要和有意义的工作，它对于确定地球的含碳量，弄清岩溶动力系统、碳的全球地球化学循环过程、大气中CO_2含量增加的原因以及近年来多种并发性灾害的成因都是不可缺少的方面。
