【文章內容簡介】 防沙治沙工作的指導原則和政策體系，是推進防沙治沙工作的綱領性文件和行動指南。 2021 年 1 月 24 日，歷時三天的防治荒漠化國際會議閉幕。會議形成了主席總結報告，通過了《北京聲明》。這些法律法規應與《地方生態環境建設規劃》和《全國生態環境保護綱要》結合，認真實施，落實規劃任務，制定年度目標，定期監督檢查 ，確保取得實效。強化依法治沙。森林公安要加大對盜伐 、 濫伐森林的打擊力度，環保等相關部門也要不斷提高執法水平。推 行禁墾 、 禁牧 、 禁樵措施，制止邊治理 、 邊破壞現象。做到有法必依 、 違法必究和執法必嚴。 、光能、熱能 為沙區群眾開辟生活用能的新途徑，減少由于薪采對沙區植被資源的強烈破壞［ 9］。 結束語 土地荒漠化已經成為當前全球生態環境最重要的問題，我國也是世界上受土地荒漠化嚴重威脅和威海的國家之一。我國荒漠化土地主要在北方，不僅土地面積大，而且發展變化也大，與之有關的各種地質災害頻繁發生。截止 2021 年，全國土地荒漠化面積為 萬 km2，其中，北方地區的沙漠、沙 漠化土地和風沙化土地達 萬 km2，占全國沙漠化土地及風沙化土地面積的 %，北方地區的荒漠化形式非常嚴峻［ 6］。近幾十年來， 土地荒漠化擴展速度不斷加快，然而人們對于荒漠化的嚴重性還認識不足。因此，讓人們了解荒漠化的成因、危害和防治措施非常有必要。并且，最終實現人與自然的和諧相處，從而達到 社會經濟和環境的可持續發展。 參考文獻 [1].那波 ,賈樹海 ,劉揚 .關于荒漠化評價幾個問題的探討 [J]中國農學通報 ,2021,22(1):305310.

You may need to make a claim to an employment tribunal if: ? you don39。t agree with the disciplinary action your employer has taken against you ? your employer dismisses you and you think that you have been dismissed unfairly. For more information about dismissal and unfair dismissal, see Dismissal. You can make a claim to an employment tribunal, even if you haven39。t appealed against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal.

If you are worried about how the time limits apply to you, take advice from one of the anisations listed under Further help. Employment tribunals are less formal than some other courts, but it is still a legal process and you will need to give evidence under an oath or affirmation. Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help. If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。t charge you more than 35% of your pensation if you win the case. If you are thinking about signing up for a damagesbased agreement, you should make sure you39。re clear about the terms of the agreement. It might be best to
