What are the three lines of land and resources, and what are the three areas and two lines of land a

The delineation of the three control lines of ecological protection red line, permanent basic farmland and urban development boundary is an important part of territorial spatial planning.

The third line is the inland area, which generally refers to the Sichuan Basin region.

The three zones and two lines of land and resources refer to the areas around important residential concentration areas such as nature reserves at or above the provincial level, scenic spots at or above the provincial level, and urban planning areas at or above the county level; High-speed railways, highways, national highways, provincial highways and other important transportation arteries, coastline intuitive visual range.

The ecological control zone refers to the area within the ecological control line, with strict ecological protection as the goal, and the overall planning of the protection and utilization of ecological resources such as mountains, rivers, forests, fields, lakes and grasses, and is the area where ecological conservation and ecological construction are strengthened, and development and construction are strictly controlled. The ecological control zone is based on the ecological protection red line and the scope of the permanent basic farmland protection red line, and includes the existing ecological land such as mountains, forests, rivers and lakes with important ecological value, as well as the statutory protection space such as drinking water source protection areas, nature reserves, scenic spots, forest parks, etc., as well as some large parks and structural green spaces that play an important role in the ecological security pattern.

The concentrated construction area refers to the area within the urban development boundary and within a certain planning period, and is the area that guides the centralized layout of various urban construction projects. It includes the central urban area, the sub-center of the city, the new city, the town center area and some urban functional groups and other areas that are planned to be built in a concentrated and contiguous area.

Restricted construction areas refer to areas outside the ecological control area and concentrated construction area, which are comprehensive treatment areas for ecological protection construction, control development intensity, and promote the intensive reduction of urban and rural construction land. It includes some villages in the plain area, scattered urban construction land, special water land, agricultural land, etc.

Summary. The three zones and three lines of territorial spatial planning refer to the three control lines of urban development boundary, permanent basic farmland protection red line and ecological protection red line corresponding to the three types of space of urban space, agricultural space and ecological space.

The three zones and three lines of territorial spatial planning refer to the three control lines of urban development boundary, permanent basic farmland protection red line and ecological protection red line corresponding to the three types of space of urban space, agricultural space and ecological space.

The unified data base is based on the current objective survey data of land, sea area and island, and forms a unified working base map. If the results of the third land survey have been formed and have been identified, they can be directly used as a base map of the working base.

Legal basis: Article 2 of the Land Management Law of the People's Republic of China The People's Republic of China implements the socialist public ownership of land, that is, the system of ownership by the whole people and the collective ownership of the working people.

The State implements a system of paid use of state-owned land in accordance with the law. However, the State shall not allocate the right to use state-owned land within the scope prescribed by law.

Legal Analysis: 1. Ecological Protection Redline: Ecological protection redline refers to the area that has special and important ecological functions within the scope of ecological space and must be strictly protected, which is the bottom line and lifeline of ensuring and maintaining national ecological security.

The significance of delineating ecological protection redlines: The delineation of ecological protection redlines is a key measure to maintain national ecological security, a key measure to continuously improve environmental quality, and help to enhance the capacity for sustainable economic and social development.

2. Permanent basic farmland: Permanent basic farmland is cultivated land that is under permanent special protection to ensure national food security and the supply of important agricultural products. The significance of demarcating permanent basic farmland:

Cultivated land is the most valuable resource in China, the foundation and lifeblood of rural development and agricultural modernization, and the cornerstone of national food security. Carrying out the demarcation of permanent basic farmland is an inherent requirement for guarding the red line of cultivated land and ensuring national food security, and it is a practical action to implement the major decisions of the provincial party committee and the provincial government.

3. Urban development boundary: The urban development boundary is the regional boundary that can be concentrated on urban development and construction and focus on improving urban functions due to the needs of urban development within a certain period of time, involving cities, organized towns and various development zones.
