First, the most fundamental requirement of ecological principles for the living environment is that the ecological structure is sound and suitable for human survival and sustainable development. The planning and design of residential landscape should first focus on meeting the requirements of ecological balance and serving the construction of a good residential ecosystem. According to its importance, the scales that should be grasped in evaluating residential landscape can be divided into ecological scale, comfort scale and aesthetic scale. Among them, ecological scale is the fundamental scale to evaluate the level of community landscape. Comfortable and beautiful match the grade of the community. Different grades of residential areas can have different comfort scales and aesthetic scales. Residential areas at all levels, without exception, require a good ecological environment, and seek comfort and beauty on the basis of meeting ecological requirements. From the perspective of ecological balance, the main function of residential landscape is to adjust air quality and enrich visual experience through facilities such as green scenery, water scenery, mountain scenery and stone scenery. Of course, this does not mean that "green house" is equal to "green house". The current "green residence" is created by the protection and improvement measures of "indoor environment" and "outdoor environment", including green landscape and waterscape. But as far as landscape is concerned, the environment is mainly improved through facilities such as green scenery, water scenery, mountain scenery and stone scenery. This point should be made clear. Nowadays, people are more and more aware that the greening of residential areas should adopt the policy of "three-dimensional greening of trees, shrubs and lawns, with trees as the mainstay". This is because trees have good functions of making oxygen, shading and beautifying. Trees are more conducive to improving air quality than irrigation and grass, and have better ecological benefits. Boulevard and boulevard formed by tall trees are also more suitable for residents to rest and enjoy outdoors. In Du Fu's poem, he said, "Famous gardens are surrounded by green water, and wild bamboos are clear in the sky." Maolin and Zhu Zhu are both beautiful scenery, so you can have both comfort and beauty. The beauty mentioned here can be called "ecological beauty". A living environment with a sound ecological structure will give people a vibrant external aesthetic feeling, that is, "ecological beauty." There are various aesthetic means and orientations to beautify the living environment, but "ecological beauty" should be regarded as the highest realm and the first and main aesthetic orientation. Therefore, the author believes that with the "aesthetic" problem of living environment getting more and more attention from all sides, the aesthetic phenomenon of "ecological beauty" should be studied as a science. Second, the economic principle of residential landscape is to take into account the recent construction cost of landscaping projects-this is related to the selling price and development profit; More attention should be paid to the long-term maintenance cost, which is related to the cost of property management. It is important to adhere to economic principles. The landscape design of foreign residential quarters mostly advocates simplicity and economy, and there are few unnecessary luxury facilities. This is worth learning from. Third, the principles of culture and art I think what we should pay special attention to and strengthen the research now is the culture and art of community landscape. The landscape of the community is by no means a simple pile of grass, trees, flowers, stones and pavilions. Although there is no definite formula, it has its superb artistic law. At present, the level of gardening varies from place to place, with many fine works and some works that are not successful. The latter can be roughly divided into two categories: the first category is poor artistic level; The second category is that although the artistic level is high, some of them are too extravagant, and "going too far is not enough" cannot be regarded as success. For the first category, it is urgent to improve the artistic level of gardening. At present, great attention should be paid to preventing a tendency. In other words, I have done enough articles on residential landscape and greening and beautification, but I have not made great efforts to create the internal ecological environment of the house. The exterior looks beautiful, but the indoor environment is not satisfactory or even poor. For example, the design of sunshine, ventilation, use function, structural layout, indoor activity line and privacy does not meet the requirements of ecology, practicality and comfort. It also includes common architectural quality problems such as seepage, leakage and cracking. In this regard, residents are very annoyed and even cause disputes.
