增加绿色资源 改善省会环境（Increase green resources and improve the provincial capital environment） The increase of green resources to improve the environment of the capital In recent years, the developed countries in the world regard increasing forest resources as an important measure to improve the ecological environment, realize indirect emission reduction and create new space for industrial development. At present, the provincial capital is paying close attention to energy conservation and emission reduction with unprecedented strength. But we must soberly realize that the space for energy conservation and emission reduction is limited, and there is still great potential to increase the indirect reduction of green resources. Trees and green spaces are called lungs of the city. They play a fundamental and irreplaceable role in improving the ecological environment and maintaining ecological security. Lack of trees and lack of green land has become an important factor affecting the ecological environment of the provincial capital Shijiazhuang. The improvement of the ecological environment must be carried out from the greening. I. major problems faced by improving the ecological environment of the provincial capital 1, green quantity is insufficient. One is the green coverage rate is low. United Nations eco city standards: green coverage rate of 50%, the residential area per capita green space 28 square meters. By the end of 2007, the green coverage rate of the built-up area of Shijiazhuang was 37%, and the per capita public green area was 8.91 square meters, which was far from the standard of the United Nations eco city.
