With the growth of population, water security has become the worldwide problem combined with severe environment pollution, quick economic development and irrational water allocation. Based on sustainable development, Water resources carrying capacity (WRCC) driven from physics originally has been proposed to solve it. The measurement of WRCC can tell decision-makers that how much population the water resource can feed, what degree water resources can support the economic and so on. Because the decision-makers can make adaptive decisions based on the correct evaluation of WRCC, the ways of the assessment of WRCC are very important. This paper focuses on how to measure WRCC by selecting three typical methods, fuzzy model of comprehensive evaluation, multiple criteria analysis (MCA) and system dynamics (SD) methods. The characteristics of these methods are good at solving the multi-objective and complicated problem in common which is the trait of WRCC. The differences of them are the specific process of analysis and evaluation.

AbstractNon-native plantation can effectively conserve soil and water and improve ecological environment,but soil desiccation occurs and then changes to severe desiccation in most forest and grass lands of water-limited regions, which causes soil degradation, vegetation decline and crop failure, so it is necessary to regulate the changed relationship between plant growth and soil water. However, there is a lack of a universally accepted theory to provide guidance of sustainable use of soil water resources and sustainable management of forest and sustainable produce of crop in such regions. The theory of regulating the relationship between plant growth and soil water in water-limited regions includes the Soil Water Resources Use Limit by Plant (SWRULP) and Soil Water Carrying Capacity for Vegetation (SWCCV). The SWCCV is the population in a plant population or density of indicator plants in a plant community when the soil water supply is equal to soil water consumption in the root zone and a given time, and changes with plant community type, location and time. The degree of coverage, productivity and benefits of a plant community when population quantity of an indicator plant equals SWCCV should be the theoretical basis for ensuring sustainable use of soil water resources and sustainable development of forest.

Water resources play an important role in the natural environment, which is an irreplaceable resource for the survival and development of human society. Taking water resources as the research object, combined with the demand of social and economic development for water resources, this paper carried out the research on the evaluation method of cultivated land scale and urban construction scale under the constraints of water resources in Jinzhou. The results show that: the scale of cultivated land is 7215.98-7843.20km2, which is in surplus. Heishan County has the largest scale of cultivated land and Guta District has the smallest scale of cultivated land. The urban construction land scale is 229.89-279.02 km2, which is in surplus. Taihe District and Yixian County are overloaded, and the rest are surplus. The evaluation results can support the determination and decomposition of planning objectives and indicators, and provide an important scientific basis for the implementation of local land spatial planning.
