摘要：由于输电线路的分布范围较大 ,在没有参照物的情况下 ,准确记录故障发生的位置比较困难。为此 ,根据电力线路巡检的业务特点 ,基于palm硬件平台、GPS和GSM无线网络传输 ,成功地开发出了一套电力线路巡检系统。

摘要：To examine the REDD+ (Reducing Emissions from Deforestation and Forest Degradation) program as an alternative to an oil palm plantation in West Kutai district of East Kalimantan, we determined the profitability of land use and REDD+, and the land use preferences and practices of the local people, as well as their participation in and preferences for forestry programs. Our findings indicate the following: 1) the profitability of an oil palm plantation was higher than that from other land uses and the REDD+ program;2) the local preferences for land uses were mostly consistent with the profitability of the land uses, except for oil palm plantation due to non-financial concerns;3) the local people combined each land use in accordance with their various needs;and 4) the local people were interested in a Forest and Land Rehabilitation (RHL) program in nonforestry zones. Considering these evidences, an improved RHL program based on an intensive agroforestry system and a conservation-based REDD+ program based on existing customary conservation forest management by the local people are proposed. Given the high opportunity cost and the low preference for an oil palm plantation, designing the REDD+ program by paying attention to the non-financial benefits for a community is a way forward. To enhance the non-financial benefits, it is important to take into consideration local preferences and livelihood activities in designing the REDD+ program. This study also implies the need for a reconsideration of the position of participation of local people in the safeguards of REDD+.

摘要：The original surveying tools and methods are backward and low efficient and they will also generate lots of errors in the National secondary land surveying. MapSUV rural land surveying palm mapping system (MapSUV palm mapping system) based on 3S techniques, combines MapGIS rural land surveying database management system. It supports the spatial location information collection and attributes data entry. By combining with GPS receiver, it ensures high accuracy in small volume, which greatly facilitates land surveying. This paper main researched system structure, function module design and key techniques. It introduced the practical process of map spot attribute checking and map spot boundary. Then it gave the application assessment. The results shows that this system greatly improves the work efficiency of outdoor surveying and shorten the time of land surveying, database build and updating.
