An approach to the fluctuation mechanism of ecotone

In this paper,the relationship among land productivity,population pressure and the fluctuation mechanism of ecotone is analyzed,taking coumties and banners of southeast Inner Mongolia plateau as an example,which is the most fragile part in the farming and husbandry interleaving belt of north China due to its severe desertification degree and low level of economic development.The Cv for the total output value of agriculture decreases from southeast to northwest,with the same rule as which the overloading population cumulated distributes,and both indicators have close relation with the high linear coefficient of 0.83.These reveal the fluctuation mechanism for ecotone:fluctuation of the level of economic development is a scientific and practical measure both to weakness degree and to instability of ecotone,because it is a synthesized response to the variation of climate as well as irrational land uses,which reinforce and magnify the fluctuation.In detail,the heavier the population overloading,the severer the grassland reclamation,the stronger the dependence of regional productivity on rainfall,the lower the level of economic development,the rougher the fluctuation of ecotone,but the weaker the PRED system.

试论地震台站的组织结构和激励机制建设

本文对地震台站在新时期的台站管理进行了论述。指出在防震减灾基础建设的重要时期,地震台站的管理,首先需要转变管理理念,同时应完善组织结构建设,建立激励机制。这是完成中国地震局确定的《与时俱进、开拓创新,为全面实现地震台站的现代化而奋斗》重要工作之一。     

成矿结构体系及其钨矿找矿意义

矿床共生组合和成矿系列是古老的或研究时间较长的概念,在不同矿床类型间的成因联系研究、指导成矿预测和找矿起了不小作用。为了更利于成矿预测和指导找矿,在不同矿床(点、体,种)类型的成因联系研究基础上,进行不同矿床(点、体,种)类型的空间分布规律或空间结构形式的研究,对钨矿新一轮找矿尤为重要。为此,本文首次提出成矿结构体系概念,并对其主要特征、类型、形成机制、钨矿成矿结构体系及其找矿意义进行探讨。

Can Forest-protection carbon projects improve rural livelihoods? Analysis of the Noel Kempff Mercado climate action project,Bolivia

We studied the Noel KempffMercado Climate Action Project (NKMCAP),Bolivia, to assess whether forestprotection carbon (C) projects cansignificantly benefit local people. Wehypothesized that forest protection canonly securely deliver C if significantstakeholders are meaningfully andtransparently involved, traditional orcustomary rights are recognized and theirloss compensated for, and there are directlinkages between conservation anddevelopment objective. Our researchfocused on 53 members of the communities ofFlorida, Porvenir and Piso Firme and 36secondary stakeholders. In each of thevillages we held half-day meetings withcommunity leaders, complemented bysemi-structured one-hour interviews with 5,10, and 7 families, representing 20%, 10%and 8% of each community. The long-termimpact of the NKMCAP on the localcommunities may well be positive. However,in the short run, certain sections of thelocal communities are financially poorer. Forest protection projects clearly have thepotential to sequester C, protectbiodiversity and simultaneously contributeto sustainable rural development, but ifthey really are to improve rurallivelihoods, they must be designed andimplemented carefully and participatively.
