Evaluation of development and utilization of waterresources in the irrigated areas show that it is extremely necessary to save water, and that joint use ofthe four kinds of water resources can avoid loss in agricultural production due to less water of theYellow River and drought in the local areas.
This paper applied the theory of sustainable development,analyzed the situation of the agricultural resources and the main problems existing in their utilization,and put forward the countermeasures for the sustainable utilization of agricultural resources in Shandong Province.
In the light of the principles of index selection for sustainable utilization evaluation of rural resources, 3 levels and 30 indexes were offered. Index were judged by Main Component Analysis Method, furthermore, the index system for sustainable utilization evaluation of rural resources was established.
The underground space as a natural resource is expounded from the viewpoint of science of natural resource and utilization of urban space, the basic conception, target, content and method of evaluation of underground space resource are defined and the relationship between evaluation and urban planning as well as its practical application are expounded.
In order to improve the utilization of light, the technologies of implantation of transition metal ions (V+ and Cr+) and electron beam irradiation to deposit noble metal particles (Ag and Pt) were used.
Dynamic multicast traffic grooming in wavelength division multiplexing (WDM) networks was analyzed to minimize networkwide costs and to increase the network resource utilization.
A novel bandwidth allocation strategy along with a connection admission control technique was proposed to improve the utilization of network resources.
Simulation results show that, compared with other bandwidth allocation schemes, the proposed scheme offers very low call dropping probability for real-time connections while, at the same time, keeping resource utilization high.
Analyses and simulation results show that the new algorithm can improve the bandwidth utilization and realize the fairness for both different ONUs and services.
