Such plan usually cannot reflect the relative size of the suitability of the development and utilization of mineral resources. To solve the problem, the paper has selected the gift condition, the market condition, the technological condition,socio-economic condition and environmental condition as the starting-points to analyze the influential factors of the priority-sequence of mineral resources' development and utilization. The above 5 conditions are further specified into 9 evaluative indicators to establish an evaluation indicator system. At last,we propose a decision model of the priority sequence based on grey relational analysis method, and figure out the observation objects by the suitability index of development. Finally, the mineral resources of a certain province in China were analyzed as an example. The calculation results indicate that silver(2.0057), coal(1.9955), zinc(1.9442), cement limestone(1.9077), solvent limestone(1.5624) and other minerals in the province are suitable for development and utilization.展开更多

With the deepening of the concept of environmental protection, people have also deeply realized the importance of water environment protection, and actively carried out the development, utilization and protection of water resources, which can reduce waste while improving the efficiency of water resources. In recent years, the overall scale of global water resources has declined, which also has a certain impact on the sustainable development of social economy. After water resources monitoring, we can fully understand the distribution of water resources, water quality and other aspects, so that we can timely understand the problems and effectively control them. In order to better ensure the effect of hydrological and water resources monitoring, we should fully understand the actual situation of water environment, adopt reasonable hydrological and water resources monitoring technology and equipment, and establish a hydrological and water resources monitoring system, so as to ensure that hydrological and water resources monitoring can be carried out smoothly, improve the efficiency of water resources utilization, and better promote the development of water resources development.展开更多

The environment problems are not only economic problems, but also important political problems. And they constitute an urgent and arduous task that we meet, and need a long time to be conquered. Under the present new historical circumstances, we should establish a scientific development philosophy, strengthen the environment protection, and build up a harmonious society in which urban and rural areas are progressing coordinately.展开更多
