在現代都市開發中，土地的保護與改善成為越來越重要的議題。掛網植生、噴植、檔土支撐及土方挖填工程是幾種與此相關的最新技術。
首先，掛網植生技術是一種利用特殊織網將植物栽種在崩塌易發土地上的方法。這種技術可以有效防止土地滑坡和侵蝕，同時還能提供自然美化效果。
其次，噴植技術是一種將植物種子、肥料和土壤混合後通過噴槍噴灑到土地上，快速實現植被覆蓋的方法。這樣可以迅速恢復被開發過度的土地，提高土地的生態價值。
再者，土方支撐技術是一種利用各種材料支撐土方穩定的方法，可以應用於陡坡或土方開挖工程中。這種技術可以保證土地的穩定性和安全性。
最後，土方挖填工程是指將土地挖掘或填土來改變地形或用途的工程。通過合理的土方挖填，可以實現土地資源的最大化利用和土地的持續利用。
總的來說，這些技術的應用可以有效保護和改善土地的生態環境，促進都市可持續發展。

Title: Land Protection and Improvement Technology
Article: In modern urban development, land protection and improvement have become increasingly important issues. Hanging net vegetation, spraying, soil support, and earthwork excavation and filling construction are several latest technologies related to this.
First, hanging net vegetation technology is a method that uses special woven nets to plant vegetation on land prone to landslides. This technology can effectively prevent soil erosion and landslides, while also providing natural beautification effects.
Second, spraying technology is a method that mixes plant seeds, fertilizers, and soil and then sprays them onto the land through a spray gun to achieve rapid vegetation cover. This can quickly restore excessively developed land and increase the ecological value of the land.
Furthermore, soil support technology is a method of stabilizing soil using various materials, which can be applied to steep slopes or earthwork excavation projects. This technology can ensure the stability and safety of the land.
Finally, earthwork excavation and filling construction refers to the engineering of excavating or filling soil to change the terrain or use of the land. Through proper earthwork excavation and filling, maximal use of land resources and sustainable use of land can be achieved.
In general, the application of these technologies can effectively protect and improve the ecological environment of the land, promoting sustainable urban development.
