“…In order to achieve sustainable use of soil water resources, there should be a sustainable use indicator of soil water resources, that is to say that sustainable use indicator of soil water resources can expresses the suitable degree plant use soil water resources and it will easily be recovered. The limit is the soil water resources use limit by plants (SWRULP) [14].The SWRULP can be defined as the soil water resources in the MID when the soil water content within the MID equals the wilting coefficient of an indicator plant [6] [14] [15]. Because the soil water content changes with soil water suction at different soil depth and the variation of soil water content with soil water suction accords with the Garden equation, so we can use the Garden equation to fit soil water content and soil water suction data and establish the soil water characteristics curve and then estimate the wilting coefficient at different soil depth [5] [16].…”

The goods and services produced by forest and vegetation ecology system is the power by which human society can be promoted fast in high-quality and sustainable way. With the increase of population and economic development in water-limited regions, there is an increasing demand for the quantity and variety of forest vegetation ecosystem products and services. To meet the demands of this situation, most of the original forest has changed into farmland, non-native forest and grass land. As a result, water-plant relationship changed from equilibrium to non-equilibrium, which led to soil drought, soil degradation and vegetation decline in dry years or waste of soil water in rainy years in most of water-limited regions. In order to solve the questions and realize the sustainable utilization of soil water resources and the high quality and sustainable development of social economy, it is necessary to apply the utilization limit theory of soil water resources by plants and the theory of soil water carrying capacity for vegetation to adjust the relationship between plant growth and soil moisture to obtain the maximum yield and benefit of vegetation and serve high-quality and sustainable development.

“…The infi ltration depth equals the distance from the surface to the crossover point between the two respective soil water distribution curves of soil water with soil depth before and after the rain event (fi gure 1). The MID will occur after a continuous heavy rainfall event and a long-term cumulative infi ltration process, and can be determined by a series of twocurve methods (fi gure 2) [6,7].…”

Rice is a main food over the world. With the growing population and urbanization, the demand for the rice is increasing.To ensure the sustainable produce and market supply of rice is most important to meet the people's need of rice and the sustainable development. Most of distribution area of rice is in resources-limited regions, and sometime natural calamities infl uences rice yield,quality and market supply almost every year in resources-limited regions over the world. However, there are few reports of rice carrying capacity and sustainable produce of Rice. In this study,author review rice carrying capacity and sustainable produce of rice. In the near future, we should study the rice carrying capacity and regulated the relationship between nature resources and rice plant growth in the resources-limited regions at the right time to ensure the sustainable use of natural resources and sustainable produce of rice and market supply to serve sustainable development.

“…The available amount of branches and leaf is the branches and leaf when the density is equal to the SWCCV when the soil water supply (SWS) is equal to soil water consumption (SWC) in the root zone in the key regulating period within a growing season. Generrally, the relationship between fruit tree growth and soil water can be regulated by changing the amount of tree or plant (Guo, 2014), as for some plant, such as red plum apricot, the relationship often can be regulated by cutting some of vimens or leaf or fruit in the key regulating period within fruit expansion period because the relationship between fruit tree growth and soil water has to be regulated by changing the amount of vimens or leaf or fruit.…”

“…Soil water carrying capacity for vegetation (SWCCV) is the ability of soil water resources to bear vegetation. The SWCCV is the population quantity or density of indicator plant in a plant community when the soil water supply (SWS) is equal to soil water consumption (SWC) in the root zone in a growing season (Guo, 2014)，which is indicated by suitable amount of branches and leaves for economic forest, such as red plum apricot in red plum apricot forest because the relationship between soil water and plant growth was regulated by pruning some branches and leaves. When the soil water resources equal to SWRULP，soil water sever influence red plum apricot growth，finally size of single fruit，yield and benefit of red plum apricot.…”

Red plum apricot is the best apricot over the world. Since having been introduced into Guyuan county in 1987 from Shaanxi province, red plum apricot grows well and then has been selected as good varieties to popularize in semirid loess hilly regions because the color of red plum apricot is beautiful, aroma fragrant , and taste is the mix of sour and sweet and nutrition is rich. Since 1995, the yield, benefits and planting area of red plum apricot increase doubly, and the distribution range of red plum apricot increased from Guyuan to the whole Ningxia, and then to Gansu province and so on in the water-limited regions, China. However, there are still some problems in the sustainable produce of red plum apricot. In order to promote the development of red plum apricot and meet people's increasing demand, we should do intensive study of the relationship between red plum apricot and environment and the comparison of possible methods to reduce the bad influence of drought, low temperature and frost on quality and production of red plum apricot, and determine the soil water resources use limit by red plum apricot and the suitable leaf amount of red plum apricot when the planting density equal soil water carrying capacity for red plum apricot and select the best method to reduce or evade the bad influence of soil drought, low temperature, frost and soil drought on red plum apricot to ensure the sustainable produce of red plum apricot in Sustainable Produce of red plum apricot in water-limited regions.
