It is also a common design method used by many people engaging in landscape. However, impacted by climatic changes, the planned and designed water space often cannot be injected with running water, which makes the water resources needed to irrigate the surrounding plants cannot be supplemented by the dwindling rainwater. Hence, where the water comes from has been an annoying problem for many administrative units and designers. For landscape planning and design, natural means are commonly used to reduce the impact of sewage on environment (wetlands, overland flows and swales), not only achieving the functions of beauty and leisure but also using plants to reduce nutrients in water. It also shows that plants have the capabilities to absorb nutrients in water, and this matter can assist plants in growth benefits. As a result, under the condition that water resources are hard to obtain, by combining rainwater retention and utilization of nutrients in sewage, in addition to reducing the waste of water, the discharged sewage can be rationally used to be transferred to available resource, and further achieve the goal of sustainable water resources. On the base of a family of four, this study establishes a Water Resource Smart Internet of Things System with the functions of smart monitoring and real-time control, in order to sense the nutrient concentration (NO3-) required for stable plant growth on layers, continuously monitor demands of soil moisture, and apply to water resource analysis and plan care with the base scope through series management ends, devices and application clients on the network layer. The mode field test results show that the smart system can provide care according to different kinds of plants and offer stable and suitable soil humidity, and thus greatly reducing irrigation water consumption for plants. Compared with the traditional irrigation ways, the water conservation rate can reach above 50%. On plant growth, at the first stage, the common and drought-resistant plants for vertical greening are grown, and the green coverage ratio is 32.1% in the initial period of green wall and increases to 61.8% after 100 days; at the second stage, the plants need high moisture and high nutrient are grown, and the green coverage ratio is 32.1% in the initial period and increases to 54.7% after 37 days. The test results at both stages all bring obvious growth benefits for plants and verify that plants can grow well if soil media without any nutrients are used, and the original waste and discharged sewage can be recycled to save water sources. In conclusion, establishing a Water Resource Smart Internet of Things System will be beneficial to promote the overall water resource management benefits within the base scope. In addition to avoiding the polluted water harming the environment, it has a great help for plant growth, conforming to future direction of wisdom and data development and providing reference application for management and design in relevant future fields.
