With the development of science and technology, we can apply many advanced technologies in landscape design and construction to create an ecological environment in conformity with sustainable development.
In landscape construction, designers shall try to use local materials and plants, seek for inspiration from local spiritual culture and material possessions and integrate them into landscape design works.

The grid based numerical methods have achieved remarkably, and they are currently the dominant methods in numerical simulations for solving practical problems in engineering and science.
Summary of grid-based method Lagrangian grid Eulerian grid ü Attached on the material ü Does not deal with large deformations (remesh) ü History of all the variables can be easily obtained ü Used by FEM ü Fixed in space and with time ü Not easy to treat the irregular or complicated geometries ü Difficult to tract moving boundary and interface ü Used by FDM, FVM However, the major difficulties are resulted from the use of grid/mesh, which can lead to various difficulties in dealing with problems with free surface, deformable boundary, moving interface, and extremely large deformation and crack propagation.
The state of the system is represented by a set of particles, which possess individual material properties and move according to the governing equations.
Particle approximation diagram (Shao, 2009) By deploying particles at specific positions at the initial stage before the analysis, the free surfaces, material interfaces, and moving boundaries can all be traced naturally in the process of simulation regardless the complicity of the movement of the particles.
