Land-cover changes cause a loss of natural vegetation in many parts of the world. In the Xishuangbanna （西双版纳） district （Yunnan （云南） Province）, rubber plantations replace tropical rainforests covering already an area of about 10% of the study area （2007）. There, land-use allocation is mostly driven by economic considerations. Thus, local planning authorities need decision support for land-use planning issues, which integrate socio-economic and ecological aspects. Within the NabanFrame, an agro-economic, ecological and social model was applied, which, altogether, interacted with a land allocation model via defined interfaces. Effects on the water cycle, ecological conditions as well as socio-economic should be considered by integrating the spatially distributed rainfali-runoff and water balance model AKWA-M in the model setup.

The principle aim of this work is to simulate the invasion of two invasive mosquito species Aedes aegypti and Aedes albopictus in central Europe at a landscape scale. The spatial-temporal dynamics of invasion is investigated in dependence of predation pressure, seasonal variation of ambient temperature as well as human population density. The introduction of temperature dependent entomological parameters enables the simulation of seasonal pattern of population dynamics. The influence of temperature, predation pressure and human population density on invasion is studied in one-dimensional cases. In two dimensions, georeferenced parameters such as annual mean temperature and human population density are prepared by a geographical information system and introduced into the finite element tool COMSOL Multiphysics. The results show that under the current temperature, central Europe cannot become a permanent breeding region for Aedes aegypti. However, southwest Germany especially the regions along the Upper Rhine Valley may provide suitable habitats for the permanent establishment of Aedes albopictus. An annual temperature rise of two degrees would lead to dramatic increase of invasion speed and extension range of Aedes albopictus.

2006年,全国新型农村合作医疗制度对住院费用的平均补偿水平为23.2%,补偿水平低是新型农村合作医疗制度普遍缺乏吸引力的原因之一。提高补偿水平的基础是提高筹资水平,文章研究的目的是探索目前年人均10.0元的个人筹资标准进一步增加的可行性与可能性。研究在山东和宁夏的各3个县中进行,定量调查6147户居民,定性访谈127组对象。研究发现,人均10.0元的筹资水平占居民人均纯收入的0.2%～0.3%;各县分别有20.8%～63.9%的参合家庭愿意多缴纳参合费,这部分家庭愿意缴纳的参合费平均额为24.5～63.5元;各县人均愿意缴纳参合费的最高额为200.0～1000.0元;各县购买商业医疗保险的人口比例为5.7%～28.0%,年人均缴纳的商业保险费用为280.1～844.2元。不同的利益相关者都认为进一步提高个人筹资额是可行的,作者认为将参合费提高到50.0元是可行的。

＜正＞ The Solar Energy Program of the Sino-German Financial Cooperation on the implementation of PV Diesel Hybrid systems for mini-grid village electrification started early 2002. Step by step, the program expanded to four provinces: Yunnan, Xinjiang, Qinghai and Gansu. A joint consultant team - Projekt-consult gmbh from Germany and JKD of IEE/CAS from China - was put in charge to support local partners during implementation. Suitable villages without grid connection and complying with a set of agreed selection criteria were identified in various prefectures of the provinces. Provincial service companies in the four provinces were supported for the establishment of management regulations for appropriate O＆M schemes and fee-collection in order to assure sustainable operation. Construction companies were identified by public tenders in order to install the village power systems. Constructed in 2004, the first 26 PVH plants passed Preliminary Acceptance Inspection successfully early 2005 in Yunnan and Xinjiang. Construction of more than 150 additional PVH plants in Xinjiang and Yunnan as well as in Qinghai and Gansu Provinces is under preparation and scheduled for late 2005 to late 2006. After the village power systems have successfully passed Final Acceptance Inspection, provincial service companies will be fully responsible for their sustainable operation for the benefit of rural villagers.

Geodesy and Geodynamics 2018年第3期9卷 204-209页

The Burris Gravity MeterTM manufactured by ZLS Corporation, Austin/Texas, USA, is based on the in- vention of L^R （L. LaCoste and A. Romberg）： The ZLS （zero-length spring）. A digital feedback system （range of about 50 mGal） is used to null the beam. Now, more than 120 gravity meters of this make exist worldwide and are used successfully in exploration, volcanology, geodetic work and surveying. The sensor is made of the well-known （L＆R） metal-alloy zero-length spring providing a low drift characteristic. The drifts observed are comparable to L＆R gravimeters and are less than 0.3 mGal per month, which is much lower than the drifts known for the fused quartz sensors. The dial is calibrated every 50 regal over the entire 7000 mGal meter range. Since the gravity value is determined at these points, there are no periodic errors. By a fourth heater circuit temperature effects are totally avoided. The gravity meter is controlled via Bluetoothce either to a handheld computer （tablet） or a notebook computer. The feedback responds with high stability and accuracy. The hulling of the beam is controlled by the UltraGravTM control system which incorporates an inherently linear PWM （pulse-width modulated） electrostatic feedback system. In order to improve the handling of the gravimeter we have developed two Windows based programs： AGESfield for single measurements and AGEScont for continuous readings.
